I noticed our CDH5 cluster is not balanced and balancer role is missing. So i added via cloudera
manager new balancer role and clicked on rebalance in hdfs menu. After some time task ended
as failed.

In logs i can balancer started but when it want to start moving blocks all failed with message
2015-01-29 15:26:55,131 WARN  [pool-4-thread-4] balancer.Balancer (Balancer.java:dispatch(362))

through 10.xx.xx.14:50010: Premature EOF: no length prefix availableAny idea what is the problem
about? Cluster is working fine so i have no clue. Maybe i need restart HDFS service first?
