Andrew Wang updated HDFS-12218:
-------------------------------
Hadoop Flags: Incompatible change
Release Note:
This renames ClientProtocol#getECBlockGroupsStats to
ClientProtocol#getEcBlockGroupStats and ClientProtocol#getBlockStats to
ClientProtocol#getReplicatedBlockStats. The return-type classes have also been
similarly renamed. Their fields have also been renamed to drop the "stats"
suffix.
Additionally, ECBlockGroupStats#pendingDeletionBlockGroups has been renamed to
ECBlockGroupStats#pendingDeletionBlocks, to clarify that this is the number of
blocks, not block groups, pending deletion. The corresponding NameNode metric
has also been renamed to PendingDeletionECBlocks.
> Rename split EC / replicated block metrics in BlockManager
