Hey,

this is my hdfs-site.xml -> http://pastebin.com/qpELkwH8
this is my core-site.xml:


 
 fs.defaultFS
 hdfs://blabla-hadoop
 

 
 hadoop.tmp.dir
 /opt/hadoop/hadoop/tmp
 


I kill only the namenode process and nothing happen, then I killed zkfc 
process and the transition happend, the second namenode become active.

Thanks.

  Hi Bruno,

Could you post your configuration? Also, when you killed one of
the NN, you mean only killing the NN process or you shutdown the whole
machine?

Thanks,

Hey,

I have configured a Hadoop v2.2.0 cluster with QJM and Zookeeper for HA and
automatic failover.
But I'm having a problem. If I test the automatic failover, by killing one
of the namenodes, nothing happens. But if I kill the zkfc of that namenode,
then zookeeper elects the other namenode as active.

What can it be the problem?

Thanks.

Hi Bruno,
ha.zookeeper.quorum is a property in core-site and you have it in
hdfs-site, maybe it's your problem.
