Michael Moss created SPARK-22567: ------------------------------------ Summary: spark.mesos.executor.memoryOverhead equivalent for the Driver when running on Mesos Key: SPARK-22567 URL: https://issues.apache.org/jira/browse/SPARK-22567 Project: Spark Issue Type: Improvement Components: Mesos Affects Versions: 2.2.0 Reporter: Michael Moss Priority: Minor
spark.mesos.executor.memoryOverhead is: "The amount of additional memory, specified in MB, to be allocated per executor. By default, the overhead will be larger of either 384 or 10% of spark.executor.memory" It is important for every JVM process to have memory available to it, beyond its heap (Xmx) for native allocations. When using the MesosClusterDispatcher and running the Driver on Mesos (https://spark.apache.org/docs/latest/running-on-mesos.html#cluster-mode), it appears that the Driver's mesos sandbox is allocated with the same amount of memory (configured with spark.driver.memory) as the heap (Xmx) itself. This increases the prevalence of OOM exceptions. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
