Zhe Zhang commented on HDFS-8146:
---------------------------------
Thanks Uma. Either option looks fine to me.
Another possible code optimization is to add PB support for {{BlockTargetPair}}
and use it to PB'ficate both {{BlockCommand}} and {{BlockECRecoveryCommand}}.
> Protobuf changes for BlockECRecoveryCommand and its fields for making it
> ready for transfer to DN

> 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.
