------------------------------------
Summary: Don't use Scala classes in external shuffle service
Key: SPARK-21369
URL: https://issues.apache.org/jira/browse/SPARK-21369
Project: Spark
Issue Type: Bug
Components: Shuffle, YARN
Affects Versions: 2.2.0
Reporter: Shixiong Zhu
Assignee: Shixiong Zhu
Right now the external shuffle service uses Scala Tuple2. However, the Scala
library won't be shaded into the yarn shuffle assembly jar. Then when the codes
are called, it will throw ClassNotFoundException.
Right now it's safe by default because we disabled
spark.reducer.maxReqSizeShuffleToMem. However, to allow using
spark.reducer.maxReqSizeShuffleToMem, we should remove all usages of Tuples.
