Michael Armbrust updated SPARK-9700:
------------------------------------
Sprint: Spark 1.5 release (was: Spark 1.5 doc/QA sprint)
> Pick default page size more intelligently
> -----------------------------------------
>
> Key: SPARK-9700
> URL: https://issues.apache.org/jira/browse/SPARK-9700
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Davies Liu
> Assignee: Reynold Xin
> Priority: Blocker
>
> Previously, we use 64MB as the default page size, which was way too big for a
> lot of Spark applications (especially for single node).
> This patch changes it so that the default page size, if unset by the user, is
> determined by the number of cores available and the total execution memory
> available.
