Subject [jira] [Commented] (HBASE-15727) Canary Tool for Zookeeper
Date Fri, 29 Apr 2016 22:26:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15727?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15264881#comment-15264881

Matteo Bertozzi commented on HBASE-15727:

Is the -zookeeper mode exclusive? from the code looks like.
maybe some warn for the user if it tries to do -zookeeper -regionserver
like we do for -regionserver and -allRegions

other than that looks ok to me

> It would be nice to have the canary tool also monitor zookeeper.  Something simple like
doing a getData() call on zookeeper.znode.parent
> It would be nice to create clients for every instance in the quorum such that you could
monitor overloaded or poor behaving instances.
