Subject [jira] [Created] (ACCUMULO-1776) MiniAccumuloCluster has ConcurrentModificationException
Date Fri, 11 Oct 2013 20:52:42 GMT
Christopher Tubbs created ACCUMULO-1776:

             Summary: MiniAccumuloCluster has ConcurrentModificationException
                 Key: ACCUMULO-1776
             Project: Accumulo
          Issue Type: Bug
          Components: mini
            Reporter: Christopher Tubbs
             Fix For: 1.6.0

MiniAccumuloCluster throws concurrency exception in loop over tabletServerProcesses in stop().

The likely suspect is the shutdown hook that also calls stop.

stop, and other methods that modify this list (killProcess, start, exec) should be synchronized.
