Subject [jira] [Commented] (YARN-4736) Issues with HBaseTimelineWriterImpl
Date Mon, 29 Feb 2016 22:56:18 GMT

    [ https://issues.apache.org/jira/browse/YARN-4736?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15172795#comment-15172795
] 

Ted Yu commented on YARN-4736:
------------------------------

bq. so planning to test with hbase-1.0.3 tar. 

There have been more release(s) since 1.0.3 release.
e.g. you can try out 1.2.0 release.

BufferedMutatorImpl#flush() appeared in stack trace. However, if the hbase cluster was shutdown,
the flush wouldn't succeed.

I haven't seen the above issue happen on a live 1.x cluster.

> Faced some issues while running ATSv2 in single node Hadoop cluster and in the same node
had launched Hbase with embedded zookeeper.

process was not completed due to the locks.
> # Got some exception related to Hbase after application finished execution successfully.

> will attach logs and the trace for the same
