[jira] [Commented] (SPARK-3005) Spark with Mesos fine-grained mode
throws UnsupportedOperationException in MesosSchedulerBackend.killTask()
[ https://issues.apache.org/jira/browse/SPARK-3005?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14095285#comment-14095285 ]
Xu Zhongxing commented on SPARK-3005:
-------------------------------------
A related question: why does fined-grain mode and coarse-grained mode perform differently? Neither of them implement the killTask() method.

> Key: SPARK-3005
> URL: https://issues.apache.org/jira/browse/SPARK-3005
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.0.2
> Environment: Spark 1.0.2, Mesos 0.18.1, spark-cassandra-connector
> Reporter: Xu Zhongxing
>
> I am using Spark, Mesos, spark-cassandra-connector to do some work on a cassandra cluster.
> During the job running, I killed the Cassandra daemon to simulate some failure cases. This results in task failures.
> If I run the job in Mesos coarse-grained mode, the spark driver program throws an exception and shutdown cleanly.
> But when I run the job in Mesos fine-grained mode, the spark driver program hangs.
> The spark log is:
> INFO [spark-akka.actor.default-dispatcher-4] 2014-08-13 15:58:15,794 Logging.scala (line 58) Cancelling stage 1
> INFO [spark-akka.actor.default-dispatcher-4] 2014-08-13 15:58:15,797 Logging.scala (line 79) Could not cancel tasks for stage 1
