Steve Loughran commented on HADOOP-11509:
-----------------------------------------
FWIW, my experience with the YARN-679 "generic entry point" code was that any
attempt to instantiate a FileSystem instance, even indirectly, would trigger
the UGI setup. If HdfsConfiguration and, if needed YarnConfiguration hadn't
been instantiated first, you'd have an invalid filesystem/auth combo.
it was that, not the order of -D eval on the CLI, which caused problems
> change parsing sequence in GenericOptionsParser to parse -D parameters first

> In GenericOptionsParser, we need to parse -D parameter first. In that case,
> the user input parameter (through -D) can be set into configuration object
> earlier and used to process other parameters.
