The steps to reproduce this are * stop nm2 with 2048MB memory.( This I am doing to make sure that this node's heartbeat doesn't reach RM first). * now submit application. As soon as it receives first node's (nm1) heartbeat it will try to reserve memory for AM-container (2048MB). However it has only 1024MB of memory. * now start nm2 with 2048 MB memory. It hangs forever... Ideally this has two potential issues. * It should not try to reserve memory on a node manager which is never going to give requested memory. i.e. Current max capability of node manager is 1024MB but 2048MB is reserved on it. But it still does that. * Say 2048MB is reserved on nm1 but nm2 comes back with 2048MB available memory. In this case if the original request was made without any locality then scheduler should unreserve memory on nm1 and allocate requested 2048MB container on nm2. -- This message is automatically generated by JIRA.
