Looks like the join/cogroup/group is not defined on bags. I assume this is because the equality on bags is not defined.
It gives the error in map-reduce mode, but does not in local mode. Since pig is likely to get rid of custom local mode implementation and use hadoop local mode and that should fix it, I am not filing a jira. -Thejas On 11/2/09 9:19 AM, "Thejas Nair" <te...@yahoo-inc.com> wrote: > I could not find any documentation (in piglatin manual) on what the > definition of equality of bags is (or what it should be), does the order of > tuples in the bag matter ?
