[HOD] "getServiceAddr addr mapred(hdfs): not found" errors
Dear whom it may concern,
Hi, I am a novice user of Hadoop and Hadoop On Demand (HOD) system.
Currently I am using Hadoop version of 0.20.1 (I also tested with 0.18.3
version) and 4 nodes
including a head and three compute nodes. I already installed torque
resource manager
and tested it on top of my small cluster.
When I statically configured Hadoop cluster, HDFS and MapReduce could be run
without
any major problems. However, when I tried to set-up a HOD cluster, I ran
into a problem where
HDFS and MapReduce services could not be found (or started). Here is a
portion of the log-file
of Ringmaster node.

It looks like ringMaster cannot locate both of hdfs and mapred service
addresses. If you have any idea of this, please
let me know and any help will be greatly appreciated.
