Matt Cheah created SPARK-10250:
----------------------------------
Summary: Scala PairRDDFuncitons.groupByKey() should be
fault-tolerant of single large groups
Key: SPARK-10250
URL: https://issues.apache.org/jira/browse/SPARK-10250
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.4.1
Reporter: Matt Cheah
Priority: Minor
PairRDDFunctions.groupByKey() is less robust that Python's equivalent, as
PySpark's groupByKey can spill single large groups to disk. We should bring the
Scala implementation up to parity.
