Subject is time sync required among all nodes?
Date Wed, 05 Jun 2013 03:02:07 GMT
Hi,
This is very basic & fundamental question.

Is time among all nodes needs to be synced?

I've never even thought of timing in hadoop cluster but recently
experienced my servers going out of sync with time. I know hbase requires
time to by synced due to its timestamp action. But I wonder any of hadoop
functionality requires time sync. Perhaps checkpoint, namenode HA, or
datanode report, etc... hmm
