I have a service fabric application stuck in "Upgrading" mode.
The exception is:
Could not load type 'DB.IAddUser' from assembly 'DB' at
WebApi.Startup.ConfigureServices(IServiceCollection services)
My change was that of renaming the name space, from 'DB' to 'DB.Interfaces'.
This class is only used as a constructor dependency, and registered as such
Startup.cs
services.AddSingleton<IAddUser, AddUser>();
UserController.cs
private IAddUser addUser;
public UserController(IAddUser addUser){
this.addUser = addUser;
}
Why would this cause SF to get stuck?
Additionally, it only got stuck on the last upgrade domain, and not on the others.
I might be mistaken but if upgrade was successful on other upgrade domains then it is not code related issue.
Try to rollback the application upgrade and upgrade again:
Start-ServiceFabricApplicationRollback -ApplicationName fabric:/MyApp
documentation
It turns out that this had nothing to do with service fabric (as expected and as #SteppingRazor said).
The problem seems to be related to MSBuild/Azure devops build task, I had upgraded nuget package
Microsoft.VisualStudio.Azure.Fabric.MSBuild
from 1.6.7 to 1.6.8 and it seems that the build was still using older code (confirmed via a decompiler).
Reverting back to 1.6.7 solved the issue (albeit its just a workaround)

I've been following the 5 min how to for setting up an htap databse with tidb_tispark and everything works until I get to the section Launch TiSpark. My first issue occurs when executing the line:
docker-compose exec tispark-master /opt/spark-2.1.1-bin-hadoop2.7/bin/spark-shell
But I got around that by modifying the spark version to the version I found inside the container:
docker-compose exec tispark-master /opt/spark-2.3.3-bin-hadoop2.7/bin/spark-shell
My second issue occurs when executing the three line block:
import org.apache.spark.sql.TiContext
val ti = new TiContext(spark)
ti.tidbMapDatabase("TPCH_001")
When I run the last statement I get the following output
scala> ti.tidbMapDatabase("TPCH_001")

2019-07-11 16:14:36 WARN ObjectStore:568 - Failed to get database global_temp, returning NoSuchObjectException
This doesn't prevent me from running the query:
spark.sql("select * from nation").show(30);
But when I follow the further steps of the tutorial to modify the db from MySQL, the changes are not reflected immediately in Spark. Furthermore, at some point in the future (I believe > 5 minutes later), the row that was modified stops showing up in Spark SQL queries.
I'm rather new to this kind of setup and don't really know how to debug this issue. Searches for the warnings I received weren't illuminating.
I don't know if it's helpful but when I connect MySQL this is the server version I get:
Server version: 5.7.25-TiDB-v3.0.0-rc.1-309-g8c20289c7 MySQL Community Server (Apache License 2.0)
I'm one of the main dev of TiSpark. Sorry for your bad experience with it.
Due to my docker problem, I cannot directly reproduce your issue but it seems you hit one of the bug fixed recently.
https://github.com/pingcap/tispark/pull/862/files
The tutorial document is not quite up-to-date and points to an older version. That's why it didn't work with spark 2.1.1 as in tutorial. We will update it ASAP.
Newer version of TiSpark doesn't use tidbMapDatabase anymore but hooks with catalog directly instead. Method tidbMapDatabase remains for backward compatibility. Unfortunately, the tidbMapDatabase had a bug（when we ported it from older version） that it retrieves timestamp for query only once you call the function. That causes TiSpark always uses old timestamp to do snapshot reading and newer data would never be seen by it.
In newer version of TiSpark (TiSpark 2.0+ with Spark 2.3+), databases and tables are directly hooked into catalog services and you can directly call
spark.sql("use TPCH_001").show
spark.sql("select * from nation").show
This should give you fresh data.
So try restart your Spark driver, just try the two lines of code above and see if it works.
Let me know if this fix your problem. On the other hand, we will check our docker image to make sure if it contains the fix already.
If things still get wrong, would you please help to run below code and let us know the version of TiSpark.
spark.sql("select ti_version()").show
Again, sorry for causing you trouble and thanks for trying.
EDIT
To address your comment:
The warning is due to spark itself will try to locate the database in its native catalog first and this will cause a Failed to get warning. But the failover process will delegate the search to tispark and then behave correctly. So this warning can be ignored. It's recommended that add below lines to your log4j.properties in conf folder of your spark.
log4j.logger.org.apache.hadoop.hive.metastore.ObjectStore=ERROR
We will polish the docker tutorial image soon. Thank you so much for trying.
I am running Squirrel-SQL version 3.9.0 using JDK 10 on MS-Windows 10. I have configured the Microsoft SQL server JDBC driver sqljdbc42.jar along with it's native DDLs to enable native kerberos authentication. But when I try to connect to my database, I get the message JDBC Driver class not found class java.lang.ClassNotFoundException: javax.xml.bind.DatatypeConverter. How do you fix this issue?
I was able to fix this issue by placing the jaxb-api-2.3.0.jar into squirrel-sql-3.9.0/lib folder and restarting the application.
had same problem . i updgrated everything to last version of Squirel 4.5.1 (janvier 2023) & last JDK 19 & last driver SqlServer , but problem continue to occur
i found another post on StackOverflow who asked which repository had this jaxb jar
How do I resolve Could not find artifact javax.xml.bind:jaxb-api:pom:2.3.0-b161121.1438 in central (https://repo1.maven.org/maven2)?
this is the link to jaxb jar, i added it in lib/ under squirell directory , then it worked
https://maven.java.net/#nexus-search;gav~javax.xml.bind~jaxb-api~2.3.0-b161121.1438~~
I'm trying to add mysql connector dependency to kie workbench. I added it by uploading the jar to the artifact repository and adding the dependency by going to project settings. When the service task that uses the connector executes, it's not able to load the mysql's Driver class. Here's more detail on how I'm using the service task - Service task using Hibernate
When the service task execute I get this message on the workbench - Unexpected error encountered : [com.sample.bpmn.hello:36 - GetData:3] -- Unable to build entity manager factory
When I look at wildfly's server.log, it seems the jar didn't get added properly - java.lang.ClassNotFoundException: Could not load requested class : com.mysql.jdbc.Driver
When I add the dependency on the workbench, I see the following warnings. I'm not able to figure out what they mean -
Verification of class com.mysql.jdbc.integration.c3p0.MysqlConnectionTester failed and will not be available for authoring. Please check the necessary external dependencies for this project are configured correctly.
Verification of class com.mysql.jdbc.integration.jboss.ExtendedMysqlExceptionSorter failed and will not be available for authoring. Please check the necessary external dependencies for this project are configured correctly.
Verification of class com.mysql.jdbc.integration.jboss.MysqlValidConnectionChecker failed and will not be available for authoring. Please check the necessary external dependencies for this project are configured correctly.
Please let me know if more info is needed.
Much appreciated.
[PS] - I must say that I just got started with hibernate as well with no prior experience. So it could be a basic thing I'm missing there.
I've upgraded my grails application from 1.3.9 to 2.2.3 and then to 2.3.3. I read the release and upgrade notes for 1.3.9->2.2.3 and then from 2.2.3->2.3.3
I am using OpenJDK 6, Jetty 6 and the plugin jetty 1.1, MySQL 5.5 and I have the connector library under lib
Now my issue is if I run grails clean and then grails run-app the application runs without any problems but if I stop it and run grails run-app again I get a gigantic error (see here: http://pastebin.com/36MpXhir)
I also found that changing something like adding a space somewhere in BuildConfig.groovy (anything that makes it be recompiled) makes the application run normally.
Looking at the stacktrace the first thing that puzzles me is

There are references to org.apache.tomcat even though I'm using jetty (and removed tomcat from BuildConfig.groovy).
Did anyone else encounter such a problem?
Don't put jar files in the lib directory if they're available in a public Maven repo. It's far better to download jars once and keep them in a local cache, and reuse them as needed.
The MySQL driver is used as the commented-out example in the generated BuildConfig.groovy - just un-comment it :) You might want to bump up the version to the latest, e.g.
dependencies {
runtime 'mysql:mysql-connector-java:5.1.27'
}
This is a good site for finding Maven artifacts: http://mvnrepository.com/artifact/mysql/mysql-connector-java
If you do have a jar that's not in a Maven repo (e.g. one with shared code at your company) then you can put it in the lib directory, but it's not auto-discovered. Run grails compile --refresh-dependencies to get it added to the classpath.
For me same error has occurred while running the Grails Application.Then I debug and view the code history of my code which was committed recently.
From that I found the issue that was:
Inside the controller file I send the instance with-out properly
Eg:
**def list=[personInstance.]---> error occurred.**
**render list as JSON**
Then I correct my mistake-->clean the app --> run the app
Now its working fine.
I am running a .NET 4.0 web application locally using the Visual Studio Development Server (built in web server with VS2010), and for the last couple months, my StructureMap bootstrapper file has worked perfectly.
I'm using StructureMap 2.6.1
I have not changed the Bootstrapper file or the Web.config file, and suddenly, I'm getting this strange error when trying to start up my web application.
Here is the error being thrown from the website:
it's a bit tough to read. It says:
Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.
Exception Details: System.Security.SecurityException. Request Failed.
here is the code in my bootstrapper file:
public class BootStrapper
{
public static void ConfigureStructureMap()
{
ObjectFactory.Initialize(x =>
{
x.AddRegistry<ProductRegistry>();
});
}
}
public class ProductRegistry : Registry
{
public ProductRegistry()
{
For<IFirmRepository>()
.Use<FirmRepository>().Ctor<string>("connectionString").Is(ConfigurationManager.ConnectionStrings["FeesAndFlows"].ConnectionString);
For<ICryptographyService>()
.Use<Rijndael>();
For<IUserRepository>()
.Use<UserRepository>().Ctor<string>("connectionString").Is(ConfigurationManager.ConnectionStrings["FeesAndFlows"].ConnectionString);
For<IAuthenticationService>()
.Use<AuthenticationService>();
For<ILogger>()
.Use<DatabaseLogger>();
}
}
The error is being thrown on this line:
x.AddRegistry<ProductRegistry>();
I've already tried adding each of these lines to my Web.config file, one at a time, and they didn't fix the problem:
<trust level="Full" />
and
<securityPolicy>
<trustLevel name="Full" policyFile="internal"/>
</securityPolicy>
Does anyone have any ideas or might have heard of a problem like this? It's pretty important, b/c without StructureMap starting up correctly, my entire application will not run.
Thanks,
Mike
UPDATE:
Ok, so it appears my problem is local. Other developers here can download the code, and runs it just fine on their local machines. Weird. They bootstrap StructurMap just fine and all instances are resolved...
Any ideas on why just my machine can't bootstrap StructureMap when running in debug mode locally for my web project?
Are you running the code from a network drive by any chance (ie is your documents folder redirected onto a network drive)? Are you in an enterprise environment running on a domain?
If the former it's likely that the code is running in the intranet security context. If the former isn't true but the later is, then its quite possible that a network administrator has changed the enterprise wide CAS policy.
Okay, so this was the problem. The StructureMap.dll was blocked by Win 7. I don't know how is become blocked or where it became blocked, but apparently, when I downloaded the StructureMap.zip file onto my system, the .zip file was blocked, which in turn, led to all the items extracted from the .zip file being blocked as well.
Every time I unblocked it, it went back to blocked when I tried to run the web app.
The way I fixed it was to go back to the original .zip file, unblock it, extract it, and then replace my StruectureMap.dll reference with one that was not blocked.
Insane.
I don't even know WHAT causes file to suddenly become blocked or what process in Windows 7 determines what file(s) should be blocked, but this strange operating system "feature" cost me a day's worth of work.
I had the exact same issue at the exact same place, ObjectFactory.Initialize:

Getting the latest StructureMap package from NuGet (2.6.4.1) fixed the issue.
