I run HBase cluster and see in the log file every 10 seconds this exception:
2015-12-30 20:18:10,160 ERROR org.apache.hadoop.hbase.regionserver.HRegionServer$PeriodicMemstoreFlusher: Caught exception java.util.NoSuchElementException

Maybe someone knows what does it mean?
Looks like HBase bug.
Can you point me to the bug fix?
HBase version is 1.0.0-cdh5.4.8
thanks.
PeriodicMemstoreFlusher will run into the following exception. lastStoreFlushTimeMap is populated for families, if there is no family in the table or there is no entry in lastStoreFlushTimeMap.
Hope this helps!!

I have moved one magento 2 website from one server to another, after configuration, I got below error on category pages:
1 exception(s):
Exception #0 (Exception): Recoverable Error: Argument 1 passed to Mageplaza\Core\Helper\AbstractData::__construct() must be an instance of Magento\Framework\App\Helper\Context, instance of Magento\Framework\ObjectManager\ObjectManager given, called in /SOME_PATH/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 93 and defined in /SOME_PATH/app/code/Mageplaza/Core/Helper/AbstractData.php on line 56

I have tried below things to resolve above:
Reindexing
Re-save category pages from backend
Created new category, and found its page working fine.
It seems there is a problem with database where old category urls need to be reindexed/rewritten or processed some way.
Can anyone help me to resolve this or any guide how I can troubleshoot this further?
Any help is appreciated!
Thanks
Deleting var/di directory resolves the problem. I didn't need to run any CLI command nor I need to do any cache clear stuff!
I'm trying to import a dataset using neo4j-import. Unfortunately the import fails with the following error message which is not saying much to me. Does anyone has an idea?
Thank you
The command was:

Thanks for your help, I found the bug. FYI see https://github.com/neo4j/neo4j/pull/8778 for fix.
I just started getting this error on a script that hasn't changed. Updating to boto3==1.4.3 had no effect. Doesn't look like throttling, does it? Not sure where to go with this one, any suggestions would be much appreciated.

when calling the DescribeSecurityGroups operation (reached max retries: 4):
Tags could not be retrieved.
Edited to add: As noted in comment below, this is coming from a seemingly innocuous call to describe_security_groups().
Another update: OK, this was transient and is no longer happening. Le sigh. Maybe some timeout due to network issues or something. I'll leave it up on SO for now, in case someone sees this and has a flash of insight.

Acutally, I found the solution to this problem. It means that it doesn't find the table in the database. So, I executed this schema.mysql.sql file which was under the directory blog/protected/data. And everything worked fine –
I'm running a spring/hibernate java app on tomcat and I'm seeing this funky error on update:

I recently updated my mysql connector to version 5.1.15.
Has anyone seen anything like this?
I think I encountered this once and fixed it by implementing hashCode and Equals methods for the object type returned by the query.
