jython udfs

[Stan Rosenberg]

Hi,

I have three constant udfs in jython:

@outputSchema("m:map[bag{tuple()}]")
def dummy1():
    return {"key":[("value1", "value2")]}

@outputSchema("m:map[tuple()]")
def dummy2():
    return {"key":("value1", "value2")}

# doesn't work!
@outputSchema("m:map[bag{}]")
def dummy3():
    return {"key":["value1", "value2"]}


The first two are fine. The last one which returns a map whose values
are lists does not work.  (I am getting ClassCastException:
java.lang.String cannot be cast to org.apache.pig.data.Tuple).
Could somebody explain why?

Thanks,

stan
