Subject [jira] Commented: (PIG-1046) join algorithm specification is within double quotes
Date Mon, 01 Feb 2010 15:52:57 GMT

    [ https://issues.apache.org/jira/browse/PIG-1046?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12828158#action_12828158
] 

Alan Gates commented on PIG-1046:
---------------------------------

-1.  The original intent of the JIRA was to move from double quotes to single, to match the
rest of string usage in the language.  Further discussion is needed if we want to move these
to identifiers instead.

> This fails -
> j = join l1 by $0, l2 by $0 using 'skewed';
> This works -
> j = join l1 by $0, l2 by $0 using "skewed";
> String constants are single-quoted in pig-latin. If the algorithm specification is supposed
to be a string, specifying it within single quotes should be supported.
> Alternatively, we should be using identifiers here, since these are pre-defined in pig
users will not be specifying arbitrary values that might not be valid identifier.
