Binglin Chang commented on HDFS-6506:
-------------------------------------
The failed test is not related and is tracked in HDFS-3930, actually recent
build also failed because of this.

> from the error log, the reason seems to be that newly moved block replicas
> been invalidated and deleted, so some work of the balancer are reversed.

> Normally this should not happen, when moving a block from src to dest,
> replica on src should be invalided not the dest, there should be bug inside
> related logic.
> I don't think TestBalancerWithNodeGroup#testBalancerWithNodeGroup caused
> this.
