Fei Hui commented on HDFS-14847:


[~ayushtkn] Unit Test of HDFS-14847.002.path is timed out without  the fix on 
current trunk branch after HDFS-14699.
I think maybe it is not the same issue.

I guess [~marvelrock] tends to say After HDFS-14699., the issue reported here

HuangTao commented on HDFS-14847:
-

[~ayushtkn] Yes, we had the same issue, however we have fixed it with the 
following code.
{code:java}
if (state == StoredReplicaState.LIVE) { // move here
  if (!bitSet.get(blockIndex)) {
bitSet.set(blockIndex);
//} else if (state == StoredReplicaState.LIVE) { // from here
  } else {
numReplicas.subtract(StoredReplicaState.LIVE, 1);
numReplicas.add(StoredReplicaState.REDUNDANT, 1);
  }
}
{code}
[~ferhui] I think this code can fix it too.:)
