kerberos mapreduce question
with kerberos enabled a mapreduce job "runs as" the user that submitted it.
does this mean the user that submitted the job needs to have linux accounts
on all machines on the cluster?

how does mapreduce do this (run jobs as the user)? do the tasktrackers use
secure impersonation to run-as the user?

thanks! koert
