----------------------------------
Summary: UnionRDD's UnionPartition should not reference parent RDDs
Key: SPARK-2758
URL: https://issues.apache.org/jira/browse/SPARK-2758
Project: Spark
Issue Type: Improvement
Affects Versions: 1.0.0, 1.0.1, 1.0.2
Reporter: Reynold Xin
Assignee: Reynold Xin
UnionPartition has a non-transient field referencing the parent RDD, to be used
in compute (iterator). That causes some trouble with task size because
partition objects are supposed to be small.
