Josh Elser updated HBASE-19770:
-------------------------------
Hadoop Flags: Reviewed
Release Note: Introduces a new option to the HBase shell: -r,
--return-values. When the shell is in "interactive" mode (default), the return
value of shell commands are not returned to the user as they dirty the console
output. For those who desire this functionality, the "--return-values" option
restores the old functionality of the commands passing their return value to
the user.
> Add '--return-values' option to Shell to print return values of commands in
> interactive mode

> The {{list}} command should be returning {{\['a'\]}} but is not.
> The command class itself appears to be doing the right thing -- maybe the
> retval is getting lost somewhere else?
