Subject [jira] Commented: (PIG-671) typechecker does not throw an error when multiple arguments are passed to COUNT
Date Tue, 08 Mar 2011 10:10:00 GMT

    [ https://issues.apache.org/jira/browse/PIG-671?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13003883#comment-13003883
] 

Deepak Kumar V commented on PIG-671:
------------------------------------

Here is the final approach:
Include public List<FuncSpec> getArgToFuncMapping() throws FrontendException in Count.java
which will take care of number of arguments , their data types for COUNT.

I have the patch ready and have tested it. If anyone is not working on it, can this bug be
assigned to me so that i can submit the patch for review.

> In this example, the agggregate function COUNT is passed multiple arguments and does
not throw an error.
> TEST: Aggregate_184
>  A =LOAD '/user/pig/tests/data/types/DataAll' USING PigStorage() AS ( Fint:int, Flong:long,
Fdouble:double, Ffloat:float, Fchar:chararray, Fchararray:chararray, Fbytearray:bytearray,
Fmap:map[], Fbag:BAG{ t:tuple( name, age, avg ) }, Ftuple:( name:chararray, age:int, avg:float)
);
> B =GROUP A ALL; 
> X =FOREACH B GENERATE COUNT ( A.$0, A.$0 ); 
> STORE X INTO '/user/pig/tests/results/araceli.1234381533/AggregateFunc_184.out' USING
PigStorage();
