> deadlock in a job between map and reduce cores allocation

>                 Key: YARN-3416
>                 URL: https://issues.apache.org/jira/browse/YARN-3416
>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: fairscheduler
>    Affects Versions: 2.6.0
>            Reporter: mai shurong

> I submit a  big job, which has 500 maps and 350 reduce, to a queue(fairscheduler) with
300 max cores. When the big mapreduce job is running 100% maps, the 300 reduces have occupied
300 max cores in the queue. And then, a map fails and retry, waiting for a core, while the
300 reduces are waiting for failed map to finish. So a deadlock occur. As a result, the job
is blocked, and the later job in the queue cannot run because no available cores in the queue.
> I think there is the similar issue for memory of a queue .
