Subject [jira] [Commented] (HBASE-7351) Periodic health check chore
Date Fri, 28 Dec 2012 06:36:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13540364#comment-13540364

Lars Hofhansl commented on HBASE-7351:
--------------------------------------

0.94 are (hopefully) stabilized. If you like we can can pull this into 0.94.4 (it would be
great if that could include the sample script, so people have an idea what to do with this).

> Similar to MAPREDUCE-211, region server should also have a mechanism to check the health
of the node.  It should run the health check script periodically and if there is any errors,
it should stop itself gracefully.
