Arpit Agarwal commented on HDFS-9681:
-------------------------------------
+1 for the patch. I will commit it shortly.
Using JSON to serialize the {{DiskBalancerWorkEntry}} structure sent via
protobuf messages is unusual for Hadoop but I can see how it simplifies the
code here. Protobuf would yield a more compact representation but for
{{DiskBalancerWorkEntry}} the difference would be nominal and this message will
be sent rarely.
