... another thought... do you happened to have some ungracefully terminated jobs still running in the background.. Try "hadoop job -list"
Sometimes, when I hardstop a job and restart a new one, I notice a slow down until I kill those jobs gracefully by running "hadoop job -kill <job-id> ". The job-ids are displayed by that previous command.

Hi Patai, Have you looked into verifying if it is network related, maybe see what the ping responses are to that node?
