Do you need the group-key to be concatenated ? If not, you can just group on all the three columns -
TCGroupedByFuid = group TCRaw by (SrcFuid.citingdocid,
If you want the group key to be concatenated for some reason, you can see if generating a concatenated string helps.
Which version of pig are you using ? From the stack trace, it looks like the version is an old(er) one. This issue might have been fixed in a newer version of pig.
