> TestLogRollingNoCluster fails from time to time on a rig I have running here.
> Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0
> Running org.apache.hadoop.hbase.regionserver.wal.TestLogRollingNoCluster
> Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 3.155 sec - in org.apache.hadoop.hbase.regionserver.wal.TestLogRollingNoCluster
> Results :
> Tests run: 1, Failures: 0, Errors: 0, Skipped: 0
> The test itself is a bit odd. We apparently have seen NPEs around close of a WAL while trying to sync... which I suppose makes sense if two threads involved.
> Attached patch just fails the sync silently if stream is null... lets presume it a close. Adds a sync on write of trailer too... 
> This patch seems to have gotten rid of the odd failure seen on a particular box here if I keep cycling the test.
