---------------------------------
Summary: 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.
