Corey J. Nolet commented on ACCUMULO-1776:
------------------------------------------
This should probably be changed as well:
{noformat}
for (Process tserver : tabletServerProcesses) {
if (proc.equals(tserver)) {
tabletServerProcesses.remove(tserver);
tserver.destroy();
found = true;
break;
}
}
{noformat}
> MiniAccumuloCluster has ConcurrentModificationException

> Key: ACCUMULO-1776
> URL: https://issues.apache.org/jira/browse/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.
