>
> In a 2.4 HDFS cluster, we found an issue that a completeFile call failed
> since the file's last block's three replica were in decommissioning state.
> And finally the decommissioning was stuck. We figured out the issue had been
> fixed by HDFS-11499. The fix of HDFS-11499 completes a committed block if
> usable replicas are enough in close/recovery code path. Besides that, we
> think we'd better complete a committed block in block report path if usable
> replicas are engouth. It helps the condition where a client calls
> completeFile then exit abnormally (without retry) and all its last block's
> replica DNs are in decommissioning state.
