Tsuyoshi OZAWA commented on HADOOP-11543:
-----------------------------------------
[~aw] Thank you for the clarification. Make sense. I think it's useful to
print \[--loglevel loglevel\] as usage in both trunk and branch-2, but it's
missing on trunk. My suggestion is that we should revert trunk change and add
\[--loglevel loglevel\] to usage in both hadoop and yarn command. Does this
make sense to you?
The message will be like this on both trunk and branch-2:
{code}
$ bin/hadoop
Usage: hadoop [--config confdir] [--loglevel loglevel] [COMMAND | CLASSNAME]
CLASSNAME run the class named CLASSNAME
or
where COMMAND is one of:
archive -archiveName NAME -p <parent path> <src>* <dest>
{code}
> Improve help message for hadoop/yarn command
