--------------------------------
Summary: Enable javac lint for scalac parity; fix a lot of build
warnings, 1.5.0 edition
Key: SPARK-9534
URL: https://issues.apache.org/jira/browse/SPARK-9534
Project: Spark
Issue Type: Improvement
Components: Build
Reporter: Sean Owen
Assignee: Sean Owen
Priority: Minor
For parity with the kinds of warnings scalac emits, we should turn on some of
javac's lint options. This reports, for example use of deprecated APIs and
unchecked casts as scalac does.
And it's a good time to sweep through build warnings and fix a bunch before the
release.
