Re: Container launch from appmaster
Yes, you can.

should give you a very good idea and example code about this.

But, the requirements are not hard-fixed. If the scheduler cannot find
free resources on the nodes you mention, it will try to get containers
on a different node. Despite that, the total number of containers can
be controlled by limiting the count against the entry for "*".
