----------------------------------------
Summary: Avoid unnecessary repartitioning after RDD parallelize
Key: SYSTEMML-2218
URL: https://issues.apache.org/jira/browse/SYSTEMML-2218
Project: SystemML
Issue Type: Task
Reporter: Matthias Boehm
There are cases, where spark mapmm instructions to a repartition of the input
RDD in order to ensure output partition sizes <2GB. If the input originates
from a RDD parallelize this causes unnecessary shuffle because the parallelize
could already bring it into the right number of partitions.
