-----------------------------------------
Summary: MLContext `read` Statement Value Input Error For
`cols_in_block` Argument
Key: SYSTEMML-1222
URL: https://issues.apache.org/jira/browse/SYSTEMML-1222
Project: SystemML
Issue Type: Bug
Reporter: Mike Dusenberry
The {{read}} statement has optional numeric parameters, such as
{{cols_in_block}} that expect integers. If a Scala {{Long}} is supplied as an
input variable for one of those parameters via MLContext, and type error will
occur in which an {{Int}} was expected, but a {{Long}} was received. A quick
fix is to convert to an integer with {{Long.toInt}} before passing the value
into the script via MLContext.
We should automatically cast {{Long}} to {{Int}} internally.
