Hello, I'm trying to setup hadoop on demand (HOD) on my cluster. I'm currently unable to "allocate cluster". I'm starting hod with the following command:
/usr/local/hadoop-0.20.2/hod/bin/hod -c /usr/local/hadoop-0.20.2/hod/conf/hodrc -t /b/01/vanw/hod/hadoop-0.20.2.tar.gz -o "allocate ~/hod 3" --ringmaster.log-dir=/tmp -b 4 The job starts on the nodes and I see the ringmaster running on the MotherSuperior. The ringmaster-main.log file is created, but is empty. I don't see any associated processes running on the other 2 nodes in the job. The critical errors are as follows: [2010-04-06 10:34:13,630] CRITICAL/50 hadoop:298 - Failed to retrieve 'hdfs' service address. [2010-04-06 10:34:13,631] DEBUG/10 hadoop:631 - Cleaning up cluster id 238366.jman, as cluster could not be allocated.
