Hi ,

i was looking to enable central configuration in my cluster , did the following steps

mkdir /var/mapr/configuration/hostname.com/

vi mapred-site.xml

<configuration>

<name>mapred.tasktracker.map.tasks.maximum</name>

<value>7</value>

<description>The maximum number of map tasks that will be run
simultaneously by a task tracker.

</description>

</property>

<property>

<name>mapred.tasktracker.reduce.tasks.maximum</name>

<value>3</value>

<description>The maximum number of reduce tasks that will be run
simultaneously by a task tracker.

</description>

<property>

</configuration>

and in warden.conf i enabled the centralconfig
~
and restarted the warden but nothing changes in the no.of map slots and no.of reduce slots on the bashboard
