Walter Su commented on HDFS-8702:
---------------------------------
Currently BlockManager has too much rack-related logic. It's a mess.
We can implement 2 versions of blockHasEnoughRacks(..), just like HDFS-8543 did.
Or We can start clean BlockManager (HDFS-8647)
> Erasure coding: update BlockManager.blockHasEnoughRacks(..) logic for striped
> block
