[jira] [Commented] (HBASE-22930) Set unique name to longCompactions/shortCompactions threads

    [ https://issues.apache.org/jira/browse/HBASE-22930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16922548#comment-16922548 ]

--------------------------------------

Thanks [~anoop.hbase] for looking into this issue, sorry for late reply.

ThreadFactoryBuilder internally has the its own counter, but to have the counter in the thread name we need to define the format in setNameFormat(), something like below..

{code}

new ThreadFactoryBuilder().setNameFormat(n + "-longCompactions-%d");  

{code}  

ThreadFactoryBuilder was introduced in HBASE-22881.

> Sometime observed multiple compaction threads have the same name which is misleading while analysing the log.
> Currently we just append the current timestamp which can be same for multiple threads,
