Wei-Chiu Chuang commented on HDFS-15117:
----------------------------------------

The patch itself looks good.

Historically, DistributedFileSystem is a thin client to invoke operations on 
the NameNode side, where the bulk of work is done. On the other hand, most of 
the logic in getECTopologyResultForPolicies happens on the client side. Makes 
me wonder if DistributedFileSystem is the proper place for this API.
