Junping Du commented on HDFS-4127:
----------------------------------
Hi Jing, Thanks for the comments. For calculating number of replicas, I think
you are right that totalReplicasExpected now is N-3, but should be N as log
message blow. Thus, we could update totalReplicasExpected
>From
totalReplicasExpected = numOfReplicas;
To
totalReplicasExpected = numOfReplicas + result.size();
What do you think?
> Log message is not correct in case of short of replica
