> In the LogSyncer run() we keep looping till this.isInterrupted flag is set.
> But in some cases the DFSclient is consuming the Interrupted exception.  So
> we are running into infinite loop in some shutdown cases.
> I would suggest that as we are the ones who tries to close down the
> LogSyncerThread we can introduce a variable like
> Close or shutdown and based on the state of this flag along with
> isInterrupted() we can make the thread stop.
