Aditya Kishore created HBASE-6285:
-------------------------------------

             Summary: HBase master should log INFO message when it attempts to assign a region
                 Key: HBASE-6285
                 URL: https://issues.apache.org/jira/browse/HBASE-6285
             Project: HBase
          Issue Type: Bug
          Components: master
    Affects Versions: 0.94.0
            Reporter: Aditya Kishore
            Assignee: Aditya Kishore
            Priority: Minor


With the default logging level (INFO), it is very difficult to diagnose a large HBase cluster
that is having problems assigning regions because the HBase master logs a DEBUG message when
it instructs a region-server to assign a region.

You actually have to crawl EVERY HBase region-server log to find out which node received the
request for a particular region. Further, lets say the HBase master sends the request and
something goes wrong, we might not even get a message in the region-server log.
