Invoking an already dropped user defined function does not throw Exception

[GoogleCodeExporter]

What steps will reproduce the problem?

Start asterix using managix. From Web UI run the following query

drop dataverse test if exists;
create dataverse test;
use dataverse test;

create function printName()
{
"AsterixDB Shared nothing parallel BDMS"
}

printName();

drop function test.printName@0;

for $l in dataset Metadata.Function
return $l

printName();

The last call to invoke the user defined function printName() does not throw an 
Exception, it should throw an Exception because I have already dropped the 
function and later after dropping it, I try to invoke the same function, which 
should be caught.

My first guess is that this is related to Metadata cache as invoking a dropped 
function from another session throws an exception message - unknown function

• Changed state: Accepted

[GoogleCodeExporter]

create function printName()
{
"AsterixDB Shared nothing parallel BDMS"
}

printName();  =====> REMOVE this invocation and things work fine, something 
fishy with the cache

drop function test.printName@0;

for $l in dataset Metadata.Function
return $l

printName();
