NOTE about using sending pull request on github:
================================================
Apache Ranger is currently NOT setup to use pull requests to take in the changes for commit.
Please use the apache review board to submit your code changes for review and commit. https://reviews.apache.org
Also create a jira to go along with the review and mention it in the review board review. https://issues.apache.org/jira/browse/RANGER

Build Process
=============

1. Check out the code from GIT repository

2. On the root folder, please execute the following Maven command:

   $ mvn clean compile package install
   $ mvn eclipse:eclipse

   (Ranger Admin UI tests depend on PhantomJS. If the build fails with npm or Karma errors you can either
      i. install PhantomJS dependencies for your platform (bzip2 and fontconfig)
     ii. skip JavaScript test execution: mvn -DskipJSTests ...)

3. After the above build command execution, you should see the following TAR files in the target folder:


   ranger-<version>-admin.tar.gz
   ranger-<version>-atlas-plugin.tar.gz
   ranger-<version>-hbase-plugin.tar.gz
   ranger-<version>-hdfs-plugin.tar.gz
   ranger-<version>-hive-plugin.tar.gz
   ranger-<version>-kafka-plugin.tar.gz
   ranger-<version>-kms.tar.gz
   ranger-<version>-knox-plugin.tar.gz
