Subject DataNode heartbeat average time peaks
Date Mon, 25 Mar 2013 14:43:35 GMT
Hi!

We see DataNode heartbeat average time peaks in Ganglia up to 20-70 seconds
while SecondaryNameNode performs checkpointing.
See attached screenshots please.

I would like to clarify if it is Ok, or not. And what kind of consequences
and risks it could bring up.
