This is similar to what daemontools does [1]. [1] http://cr.yp.to/daemontools.html > Regionserver restart > -------------------- > > Key: HBASE-932 > URL: https://issues.apache.org/jira/browse/HBASE-932 > Project: Hadoop HBase > Issue Type: Improvement > Reporter: stack > > If we drop a flush or we fail close a write-ahead log, we currently shutdown the regionserver (we fail because of hdfs usually). Rather than shut themselves down, how about they restart? The restart at least in the HBASE-930 might fix the issue shaking DFSClient so it gets sense again. Even is HDFS is bad, it'll come around eventually. The HRS restarting itself plus HBASE-926 fix will make for fast recovery. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
