Xiangrui Meng updated SPARK-3071:
---------------------------------
Affects Version/s: 1.4.2
Target Version/s: 1.5.0
> Increase default driver memory
> ------------------------------
>
> Key: SPARK-3071
> URL: https://issues.apache.org/jira/browse/SPARK-3071
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 1.4.2
> Reporter: Xiangrui Meng
> Assignee: Ilya Ganelin
>
> The current default is 512M, which is usually too small because user also
> uses driver to do some computation. In local mode, executor memory setting is
> ignored while only driver memory is used, which provides more incentive to
> increase the default driver memory.
> I suggest
> 1. 2GB in local mode and warn users if executor memory is set a bigger value
> 2. same as worker memory on an EC2 standalone server
