> After the fix in https://issues.apache.org/jira/browse/HDFS-6178, blockManager no longer
compute pending replication work on SBN. As part of that, it also stop removing items from
invalidateBlocks.
> blocks can still be added to invalidateBlocks on SBN as part of blockReport. As a result,
the PendingDeletionBlocks metrics will keep going up on SBN.
> To fix that, we don't need to add blocks to invalidateBlocks during blockReport for SBN.
