Ravi Prakash commented on HDFS-10217:
-------------------------------------
What is the motivation behind this Brahma? Besides I see this returns
{{(currApproxBlocksScheduled.sum() + prevApproxBlocksScheduled.sum()}} . If its
to check how busy a datanode is at present, a lot factors come into play. e.g.
the block sizes of the blocks, the heartbeat frequency, other readers, writers
etc.
> show "blockScheduled count" in datanodes table.
