---------------------------------------
Summary: Spark on Mesos not correctly setting heap overhead
Key: SPARK-3535
URL: https://issues.apache.org/jira/browse/SPARK-3535
Project: Spark
Issue Type: Bug
Components: Mesos
Affects Versions: 1.1.0
Reporter: Brenden Matthews
Spark on Mesos does account for any memory overhead. The result is that tasks
are OOM killed nearly 95% of the time.
Like with the Hadoop on Mesos project, Spark should set aside 15-25% of the
executor memory for JVM overhead.
For example, see:
