Subject HOD: JobTracker failed to initialise
Date Thu, 08 Apr 2010 18:09:53 GMT
Dear All,

I am trying to install HOD on a cluster. When I tried to allocate a new
Hadoop cluster, I got the following error:

[2010-04-08 13:47:25,304] CRITICAL/50 hadoop:303 - Cluster could not be
allocated because of the following errors.
Hodring at n0 failed with following errors:
JobTracker failed to initialise

*The log file hadoop.log in the actual compute node n0 has: *

--------------------------------------------------------------------------------------------------
It looks like that hdfs daemon failed to start, so JT has no one to
communicate with, then Jetty gave a error.

I used hadoop0.20.2, Scyld OS, the cluster uses 0-5 (n0-n5) to refer to the
back end compute node. Did anyone have this problem before? Any help will be
appreciated.
P.S. I have tmp files Jetty*** generated under /tmp on the compute nodes,
but I set all the tmp dir to /home or /scratch, any idea?
