[jira] [Commented] (SPARK-10987) yarn-cluster mode misbehaving with netty-based RPC backend

Marcelo Vanzin commented on SPARK-10987:
----------------------------------------

It may not be cluster mode per se; I ran the tests locally and the cluster mode test seems to not be running at all, because there's still a container from the previous test running, stuck at this place:

>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core, YARN

>            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)
