Walter Su updated HDFS-9275:
----------------------------
Description:
In {{ErasureCodingWorker}}, for the same block group, one task doesn't know
which internal blocks is in recovering by other tasks. We could end up with
recovering 2 identical block with same index. So, {{ReplicationMonitor}} should
wait previous work to finish before schedule another one.
This is related to the occasional failure of {{TestRecoverStripedFile}}.
