Subject [jira] [Created] (ACCUMULO-2422) Backup master can miss acquiring lock when primary exits
Date Thu, 27 Feb 2014 22:33:21 GMT
Bill Havanki created ACCUMULO-2422:
--------------------------------------

             Summary: 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: 1.5.0
            Reporter: Bill Havanki
            Priority: Critical


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.
