if I have an assert line:

assertOutput('myinput' , input_data, 'myoutput', output_data);
and in my test pig script, I dump out the var myoutput:

dump myoutput;

the UDF used in the script fails to get its parameters , i.e. for the
following script:
myinput = LOAD 'blahblah' as x: tuple(something something something);

myoutput = FOREACH myinput GENERATE myUDF(x);

dump myoutput;  ------  this causes problems

STORE myoutput INTO 'blahbbbbbbb';

does this sound like a bug?

Thanks

What Problems?
Do you have any error logs or exceptions that can be shared.

the issue is that if you have the "dump" line,  the udf "myUDF(x)" fails to
get the
parameter : as I debug into the udf, the parameter tuple.get(0) gives NULL
