Which user runs the hadoop? It should be the same you trigger the job
with.

I recently installed hadoop 0.17.0 in pseudo-distributed mode on a
MacOSX 10.5.3 system with software managed by Fink installed in /sw. I
configured hadoop to use the stock Java 1.5.0_13 installation in
/Library/Java/Home. When I attempted to run a simple map/reduce job
off of the dfs after starting up the daemons, the job failed with the
following Java error (501 is the ID of the user used to start the
hadoop daemons and run the map/reduce job):
javax.security.auth.login.LoginException: Login failed:
/sw/bin/whoami: cannot find name for user ID 501
What might be causing this to occur? Manually running /sw/bin/whoami
as the user in question returns the corresponding username.
