Subject [jira] Commented: (HBASE-932) Regionserver restart
Date Thu, 16 Oct 2008 09:08:44 GMT

    [ https://issues.apache.org/jira/browse/HBASE-932?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12640111#action_12640111

Rong-En Fan commented on HBASE-932:
-----------------------------------

I like the idea of having something to restart HRS automatically for a limit # of times. This
is similar to what daemontools does [1].

> 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.
