get rid of ADAMSparkRegistrator spam

18/01/17 08:24:55 INFO org.bdgenomics.adam.serialization.ADAMKryoRegistrator: Did not find Spark internal class. This is expected for Spark 1.

Appears hundreds of times in the log output since we upgraded ADAM. This is despite the fact that we're not using spark 1. Maybe there's a way to silence a specific logger?

I've been told that this is solvable by bumping the dataproc version from 1.1 -> 1.2. We need to update this on jenkins assuming it works fine with spark 2.2.

It might still be worth silencing this for people who are running spark 2.0.0 which is what we are doing on jenkins. (and what we officially support in our build.gradle). Ultimately we need to upgrade to spark 2.2.x #2555

This is still an issue when running with --spark-runner LOCAL, ie not in dataproc.

[lbergelson]

That makes sense because it uses the bundled spark 2.0.2
