Zhe Zhang commented on HDFS-7617:
---------------------------------
Thanks for working on this [~huizane].
As Jing explained above, we are still working on the logic to manage EC
schemas. But they will for sure be stored in XAttr of either the file or its
parent directory. IIRC we decided to keep {{dataBlockNum}} and
{{parityBlockNum}} in {{BlockInfoStriped}} to avoid frequently traversing to
file/dir level to get the info.
