> -----------------
>
> Key: SPARK-2154
> URL: https://issues.apache.org/jira/browse/SPARK-2154
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 0.8.1, 0.9.0, 1.0.0
> Environment: Spark on cluster of three nodes on Ubuntu 12.04.4 LTS
> Reporter: siva venkat gogineni
> Labels: patch
> Attachments: Sccreenhot at various states of driver ..jpg
>
>
> Worker dies when i try to submit drivers more than the allocated cores. When
> I submit 9 drivers with one core for each driver on a cluster having 8 cores
> all together the worker dies as soon as i submit the 9 the driver. It works
> fine until it reaches 8 cores, As soon as i submit 9th driver the driver
> status remains "Submitted" and the worker crashes. I understand that we
> cannot run drivers more than the allocated cores but the problem here is
> instead of the 9th driver being in queue it is being executed and as a result
> it is crashing the worker. Let me know if there is a way to get around this
> issue or is it being fixed in the upcoming version?
> Cluster Details:
> Spark 1.00
> 2 nodes with 4 cores each.
