[jira] Updated: (PIG-394) Syntax for ?: requires parens in FOREACH

["Olga Natkovich (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-394?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Olga Natkovich updated PIG-394:
-------------------------------

    Fix Version/s:     (was: 0.9.0)
                   0.10

delaying to 0.10 to let current parser changes to stabilize. We need to make paranthesis optional for bincond.

> This fails
> clean = FOREACH log {
>     ev = eventType eq '/rate/video'?'none':eventType;
>     GENERATE ev as event, 1 as cnt;
> }
> but this works
> clean = FOREACH log {
>     ev = (eventType eq '/rate/video'?'none':eventType);
>     GENERATE ev as event, 1 as cnt;
> }
> The requirement for parens is bogus.  Also, this fails with very misleading messages:
> clean = FOREACH log {
>     ev = (eventType eq '/rate/video')?'none':eventType;
>     GENERATE ev as event, 1 as cnt;
> }
> I think that the parser needs to be completely revamped to avoid this sort of strangeness.
