---------------------------------------
Summary: Input CSV file is renamed by simple load and save script
Key: SYSTEMML-2538
URL: https://issues.apache.org/jira/browse/SYSTEMML-2538
Project: SystemML
Issue Type: Bug
Components: APIs, Compiler
Affects Versions: SystemML 1.3
Reporter: Samuel Kogler
Attachments: rename_bug.dml
A simple script that reads a CSV file and writes it to an output file just
renames the input file to the output file.
This optimization should not be applied to input files but only to temporary
scratch files.
Judging from quick local checks, this bug does not seem to affect
data_type='frame' inputs, but only data_type='matrix'. Test script is attached.
Tested on current master git branch (ef8b551103085b73d0b471db9df6c5c0748f7d94)
