             Summary: yarn-cluster mode misbehaving with netty-based RPC backend
                 Key: SPARK-10987
                 URL: https://issues.apache.org/jira/browse/SPARK-10987
             Project: Spark
          Issue Type: Bug
          Components: Spark Core, YARN
    Affects Versions: 1.6.0
            Reporter: Marcelo Vanzin
            Priority: Blocker


YARN running in cluster deploy mode seems to be having issues with the new RPC backend; if you look at unit test runs, tests that run in cluster mode are taking several minutes to run, instead of the more usual 20-30 seconds.

For example, https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/43349/consoleFull:

[info] YarnClusterSuite:
[info] - run Spark in yarn-client mode (13 seconds, 953 milliseconds)
[info] - run Spark in yarn-cluster mode (6 minutes, 50 seconds)
[info] - run Spark in yarn-cluster mode unsuccessfully (1 minute, 53 seconds)
[info] - run Python application in yarn-client mode (21 seconds, 842 milliseconds)
[info] - run Python application in yarn-cluster mode (7 minutes, 0 seconds)
[info] - user class path first in client mode (1 minute, 58 seconds)
[info] - user class path first in cluster mode (4 minutes, 49 seconds)
