[jira] [Updated] (SPARK-11988) Update JPMML to 1.2.7

["Sean Owen (JIRA)" <ji...@apache.org>]

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:

> 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.
