Subject auto-failover does not work
Date Mon, 02 Dec 2013 12:04:17 GMT
Hi i
  I'm testing the HA auto-failover within hadoop-2.2.0

  The cluster can be manully failover ,however failed with the automatic
failover.
I setup the HA according to  the URL

http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/HDFSHighAvailabilityWithQJM.html

  When I test the automatic failover, I killed my active NN by kill -9
<Pid-nn>,while the standby namenode does not change to active state.
  It came out the log in my DFSZKFailoverController as [1]

 Please help me ,any suggestion will be appreciated.


Regards.
