> Reporter: dhruba borthakur

> I am seeing that when we delete a large directory that has plenty of blocks,
> the heartbeat times from datanodes increase significantly from the normal
> value of 3 seconds to as large as 50 seconds or so. The heartbeat thread in
> the Datanode deletes a bunch of blocks sequentially, this causes the
> heartbeat times to increase.
