Ayush Saxena commented on HDFS-13945:
-------------------------------------
Thanx [~knanasi] for the comment.
IIUC The heartbeat check function has much to do with the scenario of dead or
decommissioning datanodes and doesn't seems to be serving as such any good
purpose in favor of our test even before.As what we require is the reporting of
disk error which would be done as part of the write process and the count which
we would get as part of the next heart beat and this much will solve our
purpose and to deal with the heartbeat interval we were here already very well
equipped with the supplier which would provide us the liberty to wait for the
correct heartbeat.So I don't think there was or is any need of the
heartbeatCheck() function
If there seems to be any other related purpose being handled by it which I
might have missed.We can for sure add it back. :)
