> PySpark: infinite loop during external sort
> --------------------------------------------
>
> Key: SPARK-8202
> URL: https://issues.apache.org/jira/browse/SPARK-8202
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 1.4.0
> Reporter: Davies Liu
> Assignee: Davies Liu
> Priority: Critical
>
> The batch size during external sort will grow up to max 10000, then shrink down to zero, causing infinite loop.
> Given the assumption that the items usually have similar size, so we don't need to adjust the batch size after first spill.
