Hi All,

I am trying to override the value of mapred.tasktracker.map.tasks.maximum
in mapred-site.xml through my job configuration object will it reflect in
the corresponding task trackers?
or do i have to change it in mapred-site.xml following a restart for the
changes to apply?

Thanks in advance.

Cheers!
Manoj.

Hi,

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.
