I'm using win10 and I have MySQL workbench 8.0 CE. I am trying to run my SQL script to check if there's any error but after I created the SQL forward engineering script and close anything about MySQL and reopen it and tried to run the script file it shows
[WinError 32] The process cannot access the file because it is being used by another process: 'C:\Users\Ozcar\AppData\Local\Temp\tmps2jek87r.cnf'
I tried to end anything about mySQL in task manager and I use cmd to do net stop MySQL8.0 and net start MySQL8.0 also but is still not work
How am I kill all the SQL processes and restart them properly?
Thank you for everyone who answer me.
In our network, we have very clear access control for mysql database. After writing a sqoop command we discovered that sqoop is trying to connect with mysql from one of the servers in hadoop cluster. Servers in hadoop cluster will not be able to connect to mysql database.
Is there any way to tell sqoop to connect with our mysql from the local machine where we are executing our sqoop command?
Sqoop naturally runs as a map reduce job. Therefore the process which is copying the data from mysql, could run on any host on the cluster and often there will be several processes reading data from mysql concurrently.
However, I think you can run Sqoop in "local" mode to stop it running on map reduce by passing -jt local to the command, eg:
sqoop [tool-name] -jt local [tool-arguments]
However if you need to run the exports in parallel, this may be much slower.
Note, I have not tested this myself.
I have installed Hadoop and Hive with MySQL metastore. I started Hadoop daemons then I started Hive shell. The problem that I am facing is that, when I quit hive shell, using "quit" command, my Hadoop daemons are also get stopped. After then, when I restart my Hadoop daemons, using start-dfs.sh and start-yarn.sh, then the NameNode, DataNode and ResourceManager are not starting. What is the problem with my configurations? Can anyone help me out?
Oh! I got it!
The thing is, first I started the Hadoop Daemons, then I checked to ensure, using JPS, and I got:
and after then, I issued a query using hive, to check out the available tables:
After the hive query, I again checked for the Hadoop Daemons using jps, but I got nothing on the terminal:
So, whenever I issue the Hive related stuff, daemons goes off from the terminal. I am not able to see them using jps.
Despite the daemons are not showing on the terminal, they are running at the background in fact. I confirmed this when I issued a command to create a repository in the HDFS and it got created:
I checked the user interface of the NameNode and Cluster also, It was showing all the information.
Okay! But my concern is, how to stop those background running Hadoop daemons without restarting my machine?
I have a new MacBook Pro and have installed/configured development environment to include PHP and MySql in particular. MySql Workbench works 100% and I can run queries from terminal (i.e., the command line). However, every SQL query I run in phpMyAdmin simply freezes. No matter how simple the query. The exact same query runs fine in MySql Workbench, but I much prefer phpMyAdmin.
I've followed this and reinstalled mysql and phpMyAdmin twice.

I suspect there is a permission setting somewhere.
What am I doing wrong? Why would phpMyAdmin work, but not execute queries?
Any thoughts are greatly appreciated.
I am using MySQL workbench 6.3 CE to connect to mysql database on amazon aws (rds) system. I was running a create table query that was taking too long (lot of joins), and I stopped the query, and closed the workbench from Task Manager (end process). Since that operation:
1) I can open the workbench connect to the database, but once I connect and select any table from the schema, the workbench hangs.
2) No query could be run from workbench - I have to stop the query and I get the error "Interrupt: Error 2006, Mysql server has gone away".
3) if I click on the table name in the object browser, I don't see any columns for the table.
I tried to run the queries from the command line (in the workbench, right click on the database connection and click "Start command line client" - and here, I am able to run queries without issue. However, I have connected to this database through RODBC - in R, none of the odbcCommands are working (sqlTables() hangs, etc).
I am at my wits end trying to understand whats wrong - any pointers would be wonderful.
Thanks.
Actually, I realized it was because I stopped the create table query - I don't know the mechanics, but apparently, there was a background process running. I had to kill the query and kill the connection and everything was back to normal.
Hope this helps someone some other time.
