Matthias Boehm closed SYSTEMML-2369. ------------------------------------ Resolution: Fixed Assignee: Matthias Boehm Fix Version/s: SystemML 1.2 > Incorrect nnz runtime propagation on codegen spark cell ops w/o agg > ------------------------------------------------------------------- > > Key: SYSTEMML-2369 > URL: https://issues.apache.org/jira/browse/SYSTEMML-2369 > Project: SystemML > Issue Type: Bug > Reporter: Matthias Boehm > Assignee: Matthias Boehm > Priority: Major > Fix For: SystemML 1.2 > > > The recent codegen compiler modification in SYSTEMML-2134 revealed a hidden > issue where spark codegen cell operations without aggregation wrongly > propagated the number of non-zeros of the main input into the output. This > can lead to incorrect results if the main input is empty but the cell > operation is sparse-unsafe. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
