Ajay Viswanathan commented on SPARK-2020:
-----------------------------------------
Do I have to use Java 8 to rectify this error?
> Spark 1.0.0 fails to run in coarse-grained mesos mode
> -----------------------------------------------------
>
> Key: SPARK-2020
> URL: https://issues.apache.org/jira/browse/SPARK-2020
> Project: Spark
> Issue Type: Bug
> Components: Mesos
> Affects Versions: 1.0.0
> Environment: Ubuntu 14.04, 64-bit
> 8GB RAM
> Reporter: Ajay Viswanathan
>
> I am using Mesos to run Spark applications on a cluster.
> Earlier, in Spark 0.9.1 and below, I could run tasks in coarse-grained more
> on the workers; but now, when I try to do the same in Spark 1.0.0, I get an
> exception preventing me from running the tasks. Fine-grained mode works fine
> in Spark 1.0.0 though.
