Patches on MAPREDUCE-4172 (for MR-relevant projects) that requires to run off of Hadoop Common project for Hadoop QA.
One sub-task per hadoop-tools submodule will be added here for reviews.
Clean up java warnings in the hadoop-mapreduce-project sub projects
Patches were too broad and have gone stale. Will address these forms of issue over separate, smaller and more divided JIRAs in future.
Closing out parent JIRA MAPREDUCE-4172, and hence closing out this.
