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 -- *Benjamin Kim* *benkimkimben at gmail*
