Summary: Codegen spark row ops failing w/ index-out-of-bounds
Key: SYSTEMML-1977
URL: https://issues.apache.org/jira/browse/SYSTEMML-1977
Project: SystemML
Issue Type: Bug
Reporter: Matthias Boehm
On Kmeans, the fusion heuristic fnr is failing with index of of bounds on
distributed (i.e., spark) codegen row operations. The root cause is misplaced
meta data management, that implicitly assumes that the first side input is
broadcast, which fails if this side input is also large and taken as an
additional rdd input.
