Subject [jira] [Commented] (HBASE-19770) `list` shell command does not return an array of table names
Date Tue, 16 Jan 2018 18:15:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-19770?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16327505#comment-16327505

Mike Drob commented on HBASE-19770:

A bit confused by how the problem relates to the solution here... Can you give it another
go at explaining please, [~elserj]? The problem of not having exit status seems clear enough
to solve on it's own, but I'm not connecting the dots on how this relates to array passing.

Also, want to make sure I understand the impact - we currently have scripts that use {{-n}}
and check the exit status. Will they need to be updated to use {{-r}} as well? I think non-interactive
mode does always want it, and interactive mode can be a toggle, that's fine.

> 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?
