svn commit: r630357 [1/2] - in /incubator/pig/branches/types: ./ src/org/apache/pig/builtin/ src/org/apache/pig/data/ src/org/apache/pig/impl/builtin/ src/org/apache/pig/impl/eval/ src/org/apache/pig/impl/logicalLayer/ src/org/apache/pig/impl/mapreduce...

New Revision: 630357

URL: http://svn.apache.org/viewvc?rev=630357&view=rev
Log:
Changes to make types changes pass unit tests.  The following tests still fail:

    AlgebraicEval
        testGroupCountWithMultipleFields - fails in combiner, ok because we'll rewrite as part of pipeline.
    EvalPipeline
        testFunctionInsideFunction - fails in assertAtomic, ok because we'll rewrite how functions return their types anyway.
        testDistinct - some problem in distinct, may be ok because we'll rewrite this as part of pipeline.
    FilterOpNumeric
        testBinCond - fails because I commented out comparators, which will be totally rewritten anyway.
        testNestedBinCond - fails because I commented out comparators, which will be totally rewritten anyway.
