Subject [jira] [Created] (HBASE-20276) [shell] confirm shell REPL change and document
Date Sat, 24 Mar 2018 04:20:00 GMT
Sean Busbey created HBASE-20276:

             Summary: [shell] confirm shell REPL change and document
                 Key: HBASE-20276
                 URL: https://issues.apache.org/jira/browse/HBASE-20276
             Project: HBase
          Issue Type: Sub-task
          Components: documentation, shell
    Affects Versions: 2.0.0
            Reporter: Sean Busbey
             Fix For: 2.0.0

Feedback from [~mdrob] on HBASE-19158:

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
