> **********************************************************************
> the thread "MemStoreFlusher.0" is closing outputStream and remove it's lease ;
> other side the daemon thread "LeaseRenewer" failed to connect active nn for
> renewing lease,but got SocketTimeoutException cause of network is not
> good,so abort outputstream.
> then deadlock is made.
> and it seems not solved at Hadoop 2.7.1 .If confirmed , we can fixed the
> issue.
