Takanobu Asanuma commented on HDFS-10999:
-----------------------------------------
Thanks for updating the patch, [~manojg].
* About where I reviewed last time, except for testing, the latest patch looks
good to me.
* +1 for using two maps in {{InvalidateBlocks}}.
* Rather than modifying the existing methods in {{TestNameNodeMetrics}}, how
about simply adding a new method for safety first? We can refactor redundant
code later.
> Introduce separate stats for Replicated and Erasure Coded Blocks apart from
> the current Aggregated stats

> 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.
