Rakesh R commented on HDFS-11193:

bq. But worth checking the part on scanning blocks specifically for EC'ed files
 [~umamaheswararao] Yes, you are right. In order to do the block movement at 
the datanode, we need to construct internal block at the given index of a block 
group. I'm doing the changes and soon will upload the patch.

> Erasure coded striped files supports storage policies {{HOT, COLD, ALLSSD}}. 
> {{HdfsAdmin#satisfyStoragePolicy}} API call on a directory should consider 
> all immediate files under that directory and need to check that, the files 
> really matching with namespace storage policy. All the mismatched striped 
> blocks should be chosen for block movement.
