> Key: SPARK-9244
> URL: https://issues.apache.org/jira/browse/SPARK-9244
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Reporter: Matei Zaharia
> Assignee: Matei Zaharia
> Priority: Minor
> Fix For: 1.5.0
>
>
> There are a few memory limits that people hit often and that we could make
> higher, especially now that memory sizes have grown.
> - spark.akka.frameSize: This defaults at 10 but is often hit for map output
> statuses in large shuffles. AFAIK the memory is not fully allocated up-front,
> so we can just make this larger and still not affect jobs that never sent a
> status that large.
> - spark.executor.memory: Defaults at 512m, which is really small. We can at
> least increase it to 1g, though this is something users do need to set on
> their own.
