Arpit Agarwal commented on HDFS-5009:
-------------------------------------
Hi Junping,
Thanks for taking a look at the tasks! HDFS-4985 was primarily the protocol
change and though we updated LocatedBlock as part of that Jira we also need to
update the NameNode to populate LocatedBlock with the Storage Type. This Type
information will be received in the block reports (see HDFS-4987). I added a
dependency link.
> NameNode should expose storage type in the LocatedBlock
