---------------------------------------
Summary: Add an option to suppress the 'use yarn jar' warning or
remove it
Key: HADOOP-13335
URL: https://issues.apache.org/jira/browse/HADOOP-13335
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 2.7.0
Reporter: Siddharth Seth
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.
