Karthik Kambatla commented on YARN-1678:
----------------------------------------
Thanks Sandy. Looks good to me except for the following nit.
* If we are editing javadoc, we should add all the params. Or, we should not
add any at all.
{code}
*
* @param reserved
* Whether there's already a container reserved for this app on the node.
{code}
