Sean Owen updated SPARK-11988:
------------------------------
Target Version/s: 1.7.0
[~mengxr] the only real problem in play here is that JPMML 1.1 and 1.2 are a
little bit mutually incompatible, so shading is needed in the user app or in
Spark if different versions are used. Really, we could fix that by shading, but
this was a gentler step to at least make the default the newer 1.2 version that
people are likely to use. Still, that does change compatibility with apps using
1.1 I suppose so let's keep this for 1.7+ only.
The dependency graph is slightly improved in 1.2 since JAXB won't come in by
default:

> 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.
