The above test cases failed with the patch.
TestDistributedLogSplitting failed with too many open files. Will see if the
above failures are due to this patch.

>
> Currently AssignmentManager.handleRegion skips processing of ZK event change
> if the RS is offline. It relies on TimeoutMonitor and ServerShutdownHandler
> to process RIT.
> // Verify this is a known server
> if (!serverManager.isServerOnline(sn) &&
> !this.master.getServerName().equals(sn)) {
> LOG.warn("Attempted to handle region transition for server but " +
> "server is not online: " + Bytes.toString(data.getRegionName()));
> return;
> }
> For certain states like OPENED, OPENING, FAILED_OPEN, CLOSED, it can continue
> the progressing even if the RS is offline.
