Josh Elser commented on HBASE-19770:
------------------------------------
bq. looks like the gist was to make the behavior of shell commands more
consistent. Some commands printed output and returned results (some printed the
results too as duplicate, some didn't), some commands didn't return any result
but just printed something, etc.
Yup, totally understand why the change was made. I think, for normal users,
this is fine. That's why I've introduced this flag (default: false) to let
those of us who *know* what we're doing to keep doing things how we've been
doing them.
bq. That said, if there's a suggestion to improve shell experience in a way
more than - print lists for some selected commands, all up for it.
It would be nice if we could just control this at the IRB level, but I haven't
looked to see if it's possible to suppress the shell printing the values.

> The command class itself appears to be doing the right thing -- maybe the
