Yes, you can. http://hadoop.apache.org/common/docs/r0.23.0/hadoop-yarn/hadoop-yarn-site/WritingYarnApplications.html#Writing_an_ApplicationMaster 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 "*".
