CDP_BUILD_NUMBER is a bit of a hold-over from when Impala was donated by Cloudera that's never been fully abstracted out. It refers to a particular build of dependent components that are broadly based on an Apache branch (e.g. AVRO 1.11.1.7.3.1.0-160 would correspond to Avro 1.11.1, plus additional patches on top of it, usually bug fixes).
I don't think there's a good source to look at to determine what's in those builds. I think we'd broadly like to move Impala towards building and testing more with upstream Apache components - see USE_APACHE_COMPONENTS in https://github.com/apache/impala/blob/master/README-build.md - with an option to supply your own builds for downstream distributions to do their own build and validation. The different paces of development in these components mean we generally want to be loosely coupled to their features (not yet the case with HMS), so getting validation against multiple different versions can be valuable.
