Description

https://issues.apache.org/jira/browse/HADOOP-11257 added a 'deprecation' warning for 'hadoop jar'.

hadoop jar is used for a lot more that starting jobs. As an example - hive uses it to start all it's services (HiveServer2, the hive client, beeline etc).
Using 'yarn jar' for to start these services / tools doesn't make a lot of sense - there's no relation to yarn other than requiring the classpath to include yarn libraries.

I'd propose reverting the changes where this message is printed if YARN variables are set (leave it in the help message), or adding a mechanism which would allow users to suppress this WARNING.
