> The build has a lot of deprecation warnings. Some are new in Scala 2.12 and Java 11. We've fixed some, but I wanted to take a pass at fixing lots of easy miscellaneous ones here.
> They're too numerous and small to list here; see the pull request. Some highlights:
> - @BeanInfo is deprecated in 2.12, and BeanInfo classes are pretty ancient in Java. Instead, case classes can explicitly declare getters
> - Lots of work in the Kinesis examples to update and avoid deprecation
> - Eta expansion of zero-arg methods; foo() becomes () => foo() in many cases
> - Floating-point Range is inexact and deprecated, like 0.0 to 100.0 by 1.0
> - finalize() is finally deprecated (just needs to be suppressed)
> - StageInfo.attempId was deprecated and easiest to remove here
> I'm not now going to touch some chunks of deprecation warnings:
> - Parquet deprecations
> - Hive deprecations (particularly serde2 classes)
> - Deprecations in generated code (mostly Thriftserver CLI)
> - ProcessingTime deprecations (we may need to revive this class as internal)
> - many MLlib deprecations because they concern methods that may be removed anyway
> - a few Kinesis deprecations I couldn't figure out
> - Mesos get/setRole, which I don't know well
> - Kafka/ZK deprecations (e.g. poll())
> - a few other ones that will probably resolve by deleting a deprecated method
