Hey folks,

i m facing a problem, with job Tracker URL, actually  i added a node to the
cluster and after sometime i restart the cluster,  then i found that my job
tracker is showing  recent added node in *nodes * but rest of nodes are not
available not even in *blacklist. *
*
*
can any1 have any idea why its happening.
Thanks and regards
Vikas Srivastava

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?

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.
