---------------------------------

             Summary: RegionServer was blocked while aborting
                 Key: HBASE-11902
                 URL: https://issues.apache.org/jira/browse/HBASE-11902
             Project: HBase
          Issue Type: Bug
          Components: regionserver, wal
    Affects Versions: 0.98.4
         Environment: hbase-0.98.4, hadoop-2.3.0-cdh5.1, jdk1.7
            Reporter: Victor Xu


Generally, regionserver automatically aborts when isHealth() returns false. But it sometimes
got blocked while aborting. I saved the jstack and logs, and found out that it was caused
by datanodes failures. The "regionserver60020" thread was blocked while closing WAL. 
This issue doesn't happen so frequently, but if it happens, it always leads to huge amount
of requests failure. The only way to do is KILL -9.
I think it's a bug, but I haven't found a decent solution. Does anyone have the same problem?
