Introduce separate stats for Replicated and Erasure Coded Blocks apart from the current Aggregated stats

Details

    Description

      Per HDFS-9857, it seems in the Hadoop 3 world, people prefer the more generic term "low redundancy" to the old-fashioned "under replicated". But this term is still being used in messages in several places, such as web ui, dfsadmin and fsck. We should probably change them to avoid confusion.

      File this jira to discuss it.
