> Key: ACCUMULO-1583
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1583
> Project: Accumulo
> Issue Type: Bug
> Affects Versions: 1.5.0
> Reporter: Christopher Tubbs
> Priority: Critical
> Fix For: 1.8.0

>
> I found this issue in the TabletServer code, where for certain operations
> (chop, compact, flush, flushTablet, getActiveCompations, getActiveScans,
> halt, loadTablet, and unloadTablet), the RPC user's permissions are checked
> (and they are expected to be the system user), and if they aren't correct,
> the TabletServer will simply voluntarily kill itself. This is a problem,
> because the TabletServer assumes it is the problem, instead of the incoming
> credentials.
> The Master may rely on this behavior to force tablets to be unloaded if a
> TServer is bad. However, it should probably just try to delete the lock in
> zookeeper instead. After all, if it can delete the lock in zookeeper, it has
> the correct configuration, and it can be assumed that the TServer is the one
> that is wrong.
> (see o.a.a.server.tabletserver.TabletServer.checkPermission())
