Andrew Wang resolved HDFS-8672.
-------------------------------
    Resolution: Duplicate

Closing this as I believe it dupes HDFS-10999 which Manoj completed.

> 1. {{MissingBlocks}} metric is updated in HDFS-8461 so it includes striped blocks.
> 2. {{CorruptBlocks}} metric is updated in HDFS-8619 so it includes striped blocks.
> 3. {{UnderReplicatedBlocks}} and {{PendingReplicationBlocks}} includes striped blocks (HDFS-7912).
> This jira aims to seperate striped blocks count from {{UnderReplicatedBlocks}} count.
> EC file recovery need coding. It's more expensive than block duplication.
> It's necessary to seperate striped blocks count from UnderReplicatedBlocks count. So user can know what's going on.
