Hi, I am using Yarn and facing some custom requirements which seem not supported yet: Currently the getPriority() implementation in FSQueue and AppScheduler are all hard coded to be 1. We’d like them to reflect the real priority, say, from configuration file(or allocation file?). We’d like to restrict container(or node?) assignments of some queues, e.g. we want queueA only assigned to node with ip 10.10.10.10
From my understanding, if I want to implement these requirements, I have to modify some codes in Yarn and probably do some extension as well. Thus I may have troubles in resolving conflicts when upgrading Yarn version. So I am wondering: Is there any way to achieve those two requirements without change the code? If not, does Yarn have any plans to implement these? If not, does these requirements sound general enough so that I can finished it by ourselves and try to merge it back to the trunk? I am pretty new to Yarn, so If what I am asking sounds silly, please let me know and give the direction. Thanks. -- Cui Liqiang
