Appy commented on HBASE-19770:
------------------------------
Looking at the patch in other jira (HBASE-15965) again, 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.
It's a mess to maintain code when exceptions are norm rather than rules, what
was being suggested as alternative in that jira (i feel bad that i missed to
reply it though)
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.
> `list` shell command does not return an array of table names
