Walter Su commented on HDFS-8688:
---------------------------------
bq. So in the case all replicas are in decommission_inprogress state,
blockHasEnoughRacks might still be called. If so, blockHasEnoughRacks currently
returns false as it couldn't find any live replica; but with the patch, it
returns true.
Oh, I see. You are right. Thanks for the explanation.
> replace shouldCheckForEnoughRacks with hasClusterEverBeenMultiRack
