Thejas M Nair commented on PIG-2516:
------------------------------------
Yes, in some use cases you would not want the whole query to fail. But in such
cases, you can write a shell command that does not result in failure. eg "rm
-f" or "rm /nosuchfile || echo 'rm failed'".
> sh command should behave like fs command

> Issue Type: Bug
> Affects Versions: 0.9.1, 0.9.2
> Reporter: Thejas M Nair
> Labels: newbie
>
> Like fs command, sh command failure should result in query failure when run
> in batch mode. In interactive mode it should result in a warning.
> Also, sh command parsing seems to be faulty, according to Daniel, parser
> generated by PigScriptParser.jj would result in sh command using GetPath(),
> ie all sh commands might not be working.
