Does anyone have succeed configured failover namenode with QJM and federation namenode? I was configure 3 namenode (hadoop1, hadoop2, hadoop3) with hadoop1 is active and hadoop2 as a standby for failover, and hadoop3 as other federation namenode with both namenode before (hadoop1 and hadoop2) but when I start the cluster, it won't work with both (federation and failover) feature, just only one feature will be work (failover or federation), what should I do? Thank's before. Note: I used hadoop 2.5.1
