>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6659
>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: mr-am
>    Affects Versions: 2.6.0

> MR Application master waits for very long time to cleanup and relaunch the 
> tasks on lost nodes. Wait time is actually 2.5 hours 
> (ipc.client.connect.max.retries * ipc.client.connect.max.retries.on.timeouts 
> * ipc.client.connect.timeout = 10 * 45 * 20 = 9000 seconds = 2.5 hours)
> Some similar issue related in RM-AM rpc protocol is fixed in YARN-3809.
> As fixed in YARN-3809, we may need to introduce new configurations to control 
> this RPC retry behavior.
> Also, I feel this total retry time should honor and capped maximum to global 
> task time out (mapreduce.task.timeout = 600000 default)
