> Key: PIG-1765
> URL: https://issues.apache.org/jira/browse/PIG-1765
> Project: Pig
> Issue Type: Sub-task
> Reporter: Thejas M Nair
> Assignee: Xuefu Zhang
>
> In new parser changes, the following statements are treated as same -
> f = foreach l generate a as aa :int; -- here the column is now called aa and has type int
> f = foreach l generate a as (aa :int); -- this should mean that the column has type "tuple with column aa of type int"
> With old parser the 2nd statement results in syntax error, which is fine, because it requires name part .
> The parenthesis represent tuple in pig. We should deprecate support for load statement that takes schema without the parenthesis part , such as following example -
> l = load 'x' as a:int -- It should be as (a :int) , it is treated as such but this is inconsistent syntax.
