Kengo Seki commented on HADOOP-7947:
------------------------------------
I have another idea. We add a new constructor like 'public
GenericOptionsParser(String[] args, boolean flag)' so as to utilize
GenericOptionsParser, and make it avoid calling processGeneralOptions() in
parseGeneralOptions() if the second argument is false. But I'm not sure this
idea is good or bad...
> Validate XMLs if a relevant tool is available, when using scripts

> Given that we are locked down to using only XML for configuration and most of
> the administrators need to manage it by themselves (unless a tool that
> manages for you is used), it would be good to also validate the provided
> config XML (*-site.xml) files with a tool like {{xmllint}} or maybe Xerces
> somehow, when running a command or (at least) when starting up daemons.
> We should use this only if a relevant tool is available, and optionally be
> silent if the env. requests.
