Re: jobtracker url(Critical)
Vikas, Have you ensured your non-appearing tasktracker services are started/alive and carry no communication errors in their logs? Did you perhaps bring up a firewall accidentally, that was not present before?

Re: jobtracker url(Critical)
Task tracker sometimes so not clean up their mapred temp directories well if that is the case the tt on startup can spent many minutes deleting files. I use find to delete files older then a couple of days.
