Hi folks!
Wanted to bring your attention to HBASE-20276 "[shell] confirm shell
REPL change and document".
tl;dr: there's a change currently in 1.4.{0..3} and 2.0.0-* that makes
us not return values from any shell commands. current consensus is
that this fundamentally breaks the shell and we should revert it. At
least one person (me) believes that we should not treat releases with
this behavior as our stable / recommend release line.
Patch shortly going in for branch-1 and newer that reverts the behavior.
Open question: should we also revert this change in branch-1.4, even
though it means the shell will behave very differently between
maintenance releases?
