can't verify an output bag with pigUnit?

[Yang <te...@gmail.com>]

pigUnit compares the serialized string of an output result against a
pre-defined expected output string.

this is a problem with DataBag output, cuz the order of elements in a bag
is not guaranteed.
So the actual output from the test script could be anything, and can't be
compared with an expected serialized string.

how could I solve this usecase?

Thanks

We don't have those yet. Take a look of some functions in
org.apache.pig.test.Util, such as checkQueryOutputsAfterSortRecursive. You
might need something port to PigUnit.
