Song, For answer to question 1. Before deallocating the node( hod deallocate ...) are you setting the HADOOP_CONF_DIR to hod allocated directory.
For answer to question 2. Yes hod need mininum 3 nodes. As one node will run with JobTracker, second node for Namenode and third and more number of nodes will be tasktracker and datanode. If you have any questions please let me know :-) Thanks, --- Peeyush ________________________________________ From: Song Liu [lamfeeli...@gmail.com] Sent: Monday, March 15, 2010 8:25 PM To: common-user@hadoop.apache.org Subject: 2 HOD Questions Hi all, I have two questions about HOD 1. I confiured and setup a HOD on one cluster, it works fine, but when I finished jobs and deallocated the nodes, I found my jobID can still be seen using "qstat", until I kill them using "qdel". Is this normal? or do I have to do this manually, or leave with that? 2. I failed to configure the HOD on another cluster using the approach shown in userguide. It fails when allocating the nodes, and shows this error: Uncaught Exception : need more than 2 values to unpack Did anyone met this message before? BTW, to make the hod script work, I commented the line 576 which is "finally". Thanks Song Liu
