> Allow no alias in Dot schema definition in Dot LogicalPlanLoader
> ----------------------------------------------------------------
>
> Key: PIG-278
> URL: https://issues.apache.org/jira/browse/PIG-278
> Project: Pig
> Issue Type: Bug
> Reporter: Pi Song
> Attachments: AllowNoAliasSchemaInDot.patch,
> AllowNoAliasSchemaInDot2.patch
>
>
> Our schema parser doesn't allow "null" alias but we have to be able to do
> that in Dot test files.
> This is a work around by introducing "[NoAlias]" keyword in schema definition
> just for Dot LogicalPlanLoader.
> Sample:-
> {noformat}
> foreach [ key="20", type="LOForEach" , schema="[NoAlias] : long, [NoAlias] :
> byteArray" ] ;
> {noformat}
> At runtime, [NoAlias] will be substituted by dummy column names before being
> sent to the parser. Subsequently those names will be replaced by "null".
> There is no changes in the actual query parser.
