Subject [jira] [Created] (ACCUMULO-4410) Master didn't not resume balancing after administrative tserver shutdown
Date Wed, 17 Aug 2016 15:31:21 GMT
Josh Elser created ACCUMULO-4410:
------------------------------------

             Summary: Master didn't not resume balancing after administrative tserver shutdown
                 Key: ACCUMULO-4410
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4410
             Project: Accumulo
          Issue Type: Bug
          Components: master
    Affects Versions: 1.8.0
            Reporter: Josh Elser
            Priority: Critical


I realized that I misconfigured a property, so, I started manually stopping each tabletserver
(using {{accumulo admin stop <host:port>}}).

This worked as intended, the tablets were migrated and the tserver was stopped:

{noformat}
2016-08-17 15:24:20,871 [master.EventCoordinator] INFO : Tablet Server shutdown requested
for jelser-accumulo-180-4.openstacklocal:59540[1568579a4b4004c]

finished
{noformat}

However, after this point, the master did not resume balancing:

{noformat}

Even after I brought a new tserver online on that host, the master still did not resume balancing:
