Hadoop 2.4.1 Verifying Automatic Failover Failed: Unable to trigger a roll of the active NN
Hi,

I have setup Hadoop 2.4.1 HA Cluster using Quorum Journal, I am verifying automatic failover, after killing the process of namenode from Active one, the name node was not failover to standby node,

Please advise
Regards
Arthur
