> 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.
