> 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.
