Subject [jira] [Commented] (HDFS-3192) Active NN should exit when it has not received a getServiceStatus() rpc from ZKFC for timeout secs
Date Wed, 04 Apr 2012 20:00:18 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3192?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13246671#comment-13246671
] 

Todd Lipcon commented on HDFS-3192:
-----------------------------------

Why add multiple stonith paths, given we need external stonith anyway? It just adds to the
complexity by increasing the number of scenarios we have to debug, etc.

That is to say: if the ZKFC dies, then it will lose its lock, and the other node will stonith
this one when it takes over. What's the benefit of having it abort itself at the same time?
In fact, it seems to be detrimental, because if it stays up, the other node can do a graceful
transitionToStandby() call rather than having to do something more drastic like a full abort.
