Subject Re: reg max map task config
Date Mon, 28 Jan 2013 05:20:55 GMT

As noted on http://hadoop.apache.org/docs/stable/cluster_setup.html#Configuring+the+Hadoop+Daemons,
and by its own name, the config 'mapred.tasktracker.map.tasks.maximum'
applies to a TaskTracker daemon and therefore needs to be applied to
its local mapred-site.xml and has to be restarted to take new values
into effect.
