Harsh J commented on HDFS-336:
------------------------------
Btw, we expose the number of blocks via metrics today. This is mostly just good
for admins wanting to see CLI outputs, but otherwise one can safely rely on the
exposed metrics.
Unsure if its worth the addition, but surely a good to have.
> dfsadmin -report should report number of blocks from datanode
