Andrew Wang updated HDFS-12206:
-------------------------------
Attachment: HDFS-12206.001.patch
Patch attached. This fixes up the naming of the public interfaces.
These changes should also be propagated down into BlockManager and classes like
LowRedundancyBlocks and InvalidateBlocks as well, but that's another big
renaming pass. I notice that BM also doesn't respect the same naming
conventions as FSN wrt what's an aggregate, replicated-only, EC-only statistic.
There's also some inaccuracy wrt "ECBlocks" vs. "ECBlockGroups" in some
variable names. I'd like to fix these separately, doing behavior changes
especially in separate JIRAs.

> Going through the split EC/replicated metrics, I think it'd be better to name
> the replicated-only metrics with "ReplicatedBlocks" rather than "BlocksStat"
> for clarity. "Stat" is also not a very descriptive name, so remove it for the
> EC blocks as well. Finally, fix some inconsistencies that were missed earlier.
