Hello,
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 like:
2015-01-29 15:26:55,131 WARNÂ [pool-4-thread-4] balancer.Balancer
(Balancer.java:dispatch(362)) - Failed to move blk_1095182943_21451284 with
size=43 from 10.xx.xx.14:50010 to 10.xx.xx.12:50010 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?
Thanks,
JV
