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
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.
