> While checking the intermittent failure in
> TestBalancerRPCDelay#testBalancerRPCDelayQpsDefault described in HDFS-15146,
> I found that the implementation of waitReplication is incorrect.
> In the last iteration, when {{correctReplFactor}} is {{false}}, the thread
> sleeps for 1 second, then a {{TimeoutException}} is thrown without check
> whether the replication was complete in the last second.
