Brahma Reddy Battula commented on HDFS-10217:
---------------------------------------------

bq.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.

Mainly for debugging purpose..It will be visible to the admins which DN's got scheduled more
blocks...Block size can be checked, heabeat frequncy also checked through last contact.
