Todd Lipcon commented on HBASE-3375:
------------------------------------
I have some antlr background too, but would prefer to use an existing shell so
we get readline, completion, history, all that for free. jline might do some of
that for us, but I've heard it's a bit of a pain.
> 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.
