Mike Drob commented on HBASE-20276:
-----------------------------------
This seems pretty severe? I can't find mention in the docs about what our
compat guarantees for shell commands are...

> [shell] confirm shell REPL change and document

> Project: HBase

> Shell:
> HBASE-19770. There was another issue opened where this was identified as a
> problem so maybe the shape will change further, but I can't find it now.

> New commentary from [~busbey]:
> This was a follow on to HBASE-15965. That change effectively makes it so none
> of our ruby wrappers can be used to build expressions in an interactive REPL.
> This is a pretty severe change (most of my tips on HBASE-15611 will break, I
> think).
> I think we should
> a) Have a DISCUSS thread, spanning dev@ and user@
> b) based on the outcome of that thread, either default to the new behavior or
> the old behavior
> c) if we keep the HBASE-15965 behavior as the default, flag it as
> incompatible, call it out in the hbase 2.0 upgrade section, and update docs
> (two examples: the output in the shell_exercises sections would be wrong, and
> the _table_variables section won't work)
> d) In either case document the new flag in the ref guide
