So, what exactly did you do?

The jobtracker takes sometime to update its list of available task trackers (I think it is the timeout of a tasktracker) ________________________________ From: Iman E <[email protected]> To: [email protected] Sent: Thursday, July 2, 2009 4:18:10 PM Subject: starting a tasktracker on a specific node in the cluster Hi all, I want to start and stop tasktrackers one at a time without using the start-mapred script which also starts the jobtracker. I have tried to do "$HADOOP_CORE_HOME"/bin/hadoop-daemons.sh --config $HADOOP_CONF_DIR --script "$bin"/mapred start tasktracker but the tasktracker starts on the same node as the jobtracker which is not exactly what I want. I expected it to get information about where to start the task tracker from the slaves file. I have also tried to run this on the node where I want the tasktracker to start but it did not work either. Any pointers how to get this running? Thanks Iman
