Steve Loughran commented on HDFS-4623:
--------------------------------------
Actually I'm wrong: {{-nonInteractive}} and {{-importCheckpoint}} are both
mixed case -and that letter "I" is the notorious troublespot for some locales.
I do need to convert NONINTERACTIVE to lower before the check. cancelling the
patch
> NameNode.parseArguments() should use EN as the locale for case checks of

> {{NameNode.parseArguments()}} uses {{equalsIgnoreCase()}} to case convert
> arguments on the command line. This will not work consistently across
> locales, especially those that don't have {{"I".toLower()=="i").
> Fix is trivial.
