[HBASE-11912] Catch some bad practices at compile time with error-prone

• Type: Sub-task
• Status: Closed
• Priority: Major
• Resolution: Fixed
• Fix Version/s: 2.0.0
• Hadoop Flags: Reviewed
• Release Note: Errors from error-prone will fail the build in the compile phase. Warnings look like Javac warnings and are counted as such by test-patch etc

Description

Google's error-prone (https://code.google.com/p/error-prone/) wraps javac with some additional static analysis that will generate additional warnings or errors at compile time if certain bug patterns (https://code.google.com/p/error-prone/wiki/BugPatterns) are detected. What's nice about this approach, as opposed to findbugs, is the compile time detection and erroring out prevent the detected problems from getting into the codebase up front.
