[jira] [Created] (HADOOP-11460) Add a way to deprecrate shell vars

Allen Wittenauer created HADOOP-11460:
-----------------------------------------

             Summary: Add a way to deprecrate shell vars
                 Key: HADOOP-11460
                 URL: https://issues.apache.org/jira/browse/HADOOP-11460
             Project: Hadoop Common
          Issue Type: New Feature
            Reporter: Allen Wittenauer


It is a very common shell pattern in 3.x to effectively replace sub-project specific vars with generics.  We should have a function that does this replacement and provides a warning to the end user that the old shell var is deprecated.  This will allow us an easier time to remove them in the future.
