Subject How to make hadoop use all nodes?
Date Thu, 19 Sep 2013 14:19:12 GMT
Hi all,

I am working with Hadoop 2.0.5 (I plan to migrate to 2.1.0 soon).
When I am starting a Job, I notice that some nodes are not used or partially used.

For example, if my nodes can hold 2 containers, I notice that some nodes are not running any
or just 1 while others are running 2.
All my nodes are configured the same way.

Is this an expected behavior (maybe in case others jobs are started) ?
Is there a configuration to change this behavior?
