Description

A few times now I've gone to build the master branch and it's failed due to Java style errors, which I've sent in PRs to fix:

• https://issues.apache.org/jira/browse/SPARK-22268
• https://issues.apache.org/jira/browse/SPARK-21875

Digging through the history a bit, it looks like this check used to run on Jenkins and was previously enabled at https://github.com/apache/spark/pull/10763 but then reverted at https://github.com/apache/spark/commit/4bcea1b8595424678aa6c92d66ba08c92e0fefe5

We should work out what it takes to enable the Java check in Jenkins so these kinds of errors are caught in CI rather than afterwards post-merge.
