Hiroshi Ikeda commented on HBASE-11902: --------------------------------------- This HBASE-11902 seems duplicate with HBASE-13592, which has been resolved. I have created a new issue HBASE-14222 about DrainBarrier. > 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.patch, hbase11902-master_v2.patch, > 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? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
