-------------------------------

             Summary: Erasure Coding: Add EC-related Metrics on NN (seperate striped blocks
count from UnderReplicatedBlocks count)
                 Key: HDFS-8672
                 URL: https://issues.apache.org/jira/browse/HDFS-8672
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Walter Su
            Assignee: Walter Su
            Priority: Minor


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.
