> Invoking {{hbase shell}}, the hbase runner launches the jruby jar directly, and so behaves differently than the traditional jruby runner. Specifically, it
> * does not respect the {{JRUBY_OPTS}} environment variable (among other things, I cannot launch the shell to use ruby-1.9 mode)
> * does not respect the {{JRUBY_HOME}} environment variable (placing things in an inconsistent state if my classpath holds the system jruby).
> This patch allows you to use an alternative jruby and to specify options to the jruby jar.
> * When the command is 'shell', adds {{$JRUBY_OPTS}} to the CLASS
> * When the command is 'shell' and {{$JRUBY_HOME}} is set, adds {{"$JRUBY_HOME/lib/jruby.jar"}} to the classpath, and sets {{-Djruby.home}} and {{-Djruby.job}} config variables.
