Vinayakumar B commented on HDFS-8146:
-------------------------------------

Thanks [~umamahesh] for the update.

bq. If we really not useful then surely we can refine it later. I think right now its ok to
keep IMO.
Sure, but please make sure that removal is done before merging, or before a release. Because
its a *required* field in PB.

+1 for the latest patch. Will commit it soon.

> As part of working on HDFS-8137, we need to prepare BlockECRecoveryCommand, BlockECRecoveryInfo,
DatanodeStorageInfo, DatanodeDescripter (We can use DatanodeInfo for proto trasfer)  should
be ready in proto format for transferring them in command. Since all this code could be straight
forward and to have better focussed review on core part, I propose to separate this part in
to this JIRA. First I will prepare all this supported classes protobuf ready and then trasnfer
them to DN as part of HDFS-8137 by including ECSchema.
