Subject [jira] [Resolved] (HDFS-3191) Active NN should exit when it cannot write to quorum number of Journal Daemons
Date Fri, 20 Jul 2012 00:33:34 GMT

     [ https://issues.apache.org/jira/browse/HDFS-3191?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Todd Lipcon resolved HDFS-3191.
-------------------------------

    Resolution: Not A Problem

I've verified in testing of the HDFS-3077 branch that the above is true. Because the shared
edits dir is marked as "required" in the configuration, if it fails to commit to a quorum,
the resulting IOE makes the namenode abort. There are also several unit tests which verify
this behavior.
