Szehon Ho commented on HIVE-6709:
---------------------------------
Sreenivasulu can correct me if wrong, but looks like running './hive --service
hiveserver2 --help' will print an 'unrecognized option' error, but as a side
effect of that error, still displays the usage. In other words, any parse
error (even one trying to display usage) displays the usage.
Up to you whether we want to document the defect, as it works in a weird way,
but definitely the usage in general is good to document.
> HiveServer2 help command is not recognizing properly.
