stack commented on HBASE-3375:
------------------------------
I haven't looked at the grammars page on ANTLR in a year or more. I know that
as soon as you dig in, that the grammars are missing key pieces or are
incomplete but nonetheless its always fun reading this page:

> Move away from jruby; build our shell elsewise either on another foundation
> or build up our own

> Key: HBASE-3375
> URL: https://issues.apache.org/jira/browse/HBASE-3375
> Project: HBase
> Issue Type: Task
> Components: shell
> Reporter: stack
> Fix For: 0.92.0
>
>
> JRuby has been sullied; its been shipping *GPL jars with a while now. A hack
> up to remove these jars is being done elsewhere (HBASE-3374). This issue is
> about casting our shell anew atop a foundation that is other than JRuby or
> writing a shell of our own from scratch.
> JRuby has gotten us this far. It provides a shell and it also was used
> scripting HBase. It would be nice if we could get scripting and shell in the
> redo.
> Apart from the licensing issue above and that the fix will be reverting our
> JRuby to a version that is no longer supported and that is old, other reasons
> to move off JRuby are that while its nice having ruby to hand when scripting,
> the JRuby complete jar is 10 or more MB in size. Its bloated at least from
> our small shell perspective.
