ACCUMULO-2422 reset watch on non-delete events
> Backup master can miss acquiring lock when primary exits
> --------------------------------------------------------
>
> Key: ACCUMULO-2422
> URL: https://issues.apache.org/jira/browse/ACCUMULO-2422
> Project: Accumulo
> Issue Type: Bug
> Components: fate, master
> Affects Versions: 1.5.1
> Reporter: Bill Havanki
> Assignee: Bill Havanki
> Priority: Critical
> Labels: failover, locking
> Fix For: 1.6.0, 1.5.2
>
>
> While running randomwalk tests with agitation for the 1.5.1 release, I've
> seen situations where a backup master that is eligible to grab the master
> lock continues to wait. When this condition arises and the other master
> restarts, both wait for the lock without success.
> I cannot reproduce the problem reliably, and I think more investigation is
> needed to see what circumstances could be causing the problem.
