             Summary: Default value for maximum nodemanager connect wait time 
is too high
                 Key: YARN-3554
                 URL: https://issues.apache.org/jira/browse/YARN-3554
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.6.0
            Reporter: Jason Lowe

The default value for yarn.client.nodemanager-connect.max-wait-ms is 900000 
msec or 15 minutes, which is way too high.  The default container expiry time 
from the RM and the default task timeout in MapReduce are both only 10 minutes.
