Villu Ruusmann commented on SPARK-11988:
----------------------------------------
The main change is that JPMML-Model 1.2.X requires Java 1.7, whereas 1.1.X
works with Java 1.6 also. If this Java version "upgrade" is supported by Spark
1.5+, then you should definitely go for it.
Java 1.7 includes JAXB runtime libraries, so that should simplify the build
also. I can remember participating in a similar discussion (somewhere in this
JIRA) earlier this spring.
> Update JPMML to 1.2.7
> ---------------------
>
> Key: SPARK-11988
> URL: https://issues.apache.org/jira/browse/SPARK-11988
> Project: Spark
> Issue Type: Improvement
> Components: ML, MLlib
> Affects Versions: 1.5.2
> Reporter: Sean Owen
> Assignee: Sean Owen
> Priority: Minor
>
> Pretty much says it all: update to the more recent JPMML 1.2.x line from
> 1.1.x.
> The API did change between the 2 versions, though all use of it is internal
> to Spark, so doesn't affect end users in theory.
> In practice, JPMML leaks into the classpath and might cause issues. My
> rationale for the change is that 1.2.x is more recent and more stable (right
> [~vfed]?) so if people are going to run into it, might as well run into
> something more modern.
> And bug fixes and more support and all that.
