several aggregate functions do not check the number of arguments and do not correctly check for a type "bag" ------------------------------------------------------------------------------------------------------------
Key: PIG-673 URL: https://issues.apache.org/jira/browse/PIG-673 Project: Pig Issue Type: Bug Environment: i686 i386 GNU/Linux Reporter: Araceli Henley DIFF expects two bags as the argument. But in this negative test case we pass: 1) there is a single argument to diff instead of two, 2) The argument should be a bag but is an int.
