Siddharth Seth commented on HADOOP-13335:
-----------------------------------------
bq. I'm pretty much going to block anything that removes the warnings. So we
can keep this open, but it isn't going to go anywhere.
On what technical grounds ?
Printing a warning like this on branch-2 can be considered incompatible. That's
ignoring the bit that the warning itself doesn't necessarily make sense.
In terms of deprecation - I already see the following in trunk.
"hadoop_deprecate_envvar YARN_OPTS HADOOP_OPTS" - What exactly are we trying to
achieve here, between the deprecation and the push for yarn jar via this
message.
> Add an option to suppress the 'use yarn jar' warning or remove it

> 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.
