------------------------------
Thanks Jing for your discussion! let's leave it firstly, and we can close it
some days later and revisit it if we need some improvement.
> Erasure coding: move dataBlockNum and parityBlockNum from BlockInfoStriped to
> INodeFile

> Key: HDFS-8059
> URL: https://issues.apache.org/jira/browse/HDFS-8059
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Affects Versions: HDFS-7285

>
> Move {{dataBlockNum}} and {{parityBlockNum}} from BlockInfoStriped to
> INodeFile, and store them in {{FileWithStripedBlocksFeature}}.
> Ideally these two nums are the same for all striped blocks in a file, and
> store them in BlockInfoStriped will waste NN memory.
