Qiang Tian updated HBASE-11902:
-------------------------------
Attachment: hbase11902-master_v3.patch
Local run passed.
based on HBASE-8208(that is why wal.sync is introduced in memstore flush), we
also need to fail the flush when getting HDFS failure.
> 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
> Assignee: Qiang Tian
> Attachments: hbase-hadoop-regionserver-hadoop461.cm6.log,

> hbase11902-master_v3.patch, jstack_hadoop461.cm6.log

> 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?
