Subject [jira] [Commented] (HBASE-9630) Add thread which detects JVM pauses like HADOOP's
Date Mon, 23 Sep 2013 09:44:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13774425#comment-13774425

Nicolas Liochon commented on HBASE-9630:

I think it might be useful to have it in the secondary master as well. For example, if the
secondary master is paused sometimes, we want to know this before it becomes the primary master.
Or if it starts to be paused when it becomes the primary, we will want to know how it was
behaving before imho.

log, it's pretty handy for diagnose, i thought it's great to have similar ability in HBase.
