Subject Add a new node into running Hadoop from the Hadoop code
Date Tue, 18 Jan 2011 19:11:55 GMT
Hi,

It is possible to add a new tasktracker node from the Hadoop code directly ?

For example I have in the slaves a list of nodes but only some of them 
are running at the moment.
I want to start a new tasktracker from the idles nodes in the slaves.
It is possible to take some actions from Hadoop directly without doing this:

$ cd path/to/hadoop
$ bin/hadoop-daemon.sh start datanode
$ bin/hadoop-daemon.sh start tasktracker


Thanks,
Robert
