[jira] [Created] (PIG-3094) ERROR 2229: Couldn't find matching uid
-1 in Pig 0.10.0
Navneet Kapur created PIG-3094:
----------------------------------
Summary: ERROR 2229: Couldn't find matching uid -1 in Pig 0.10.0
Key: PIG-3094
URL: https://issues.apache.org/jira/browse/PIG-3094
Project: Pig
Issue Type: Bug
Reporter: Navneet Kapur
Fix For: 0.10.0
I'm getting the error message:
ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2229: Couldn't find matching uid -1 for project (Name: Project Type: bytearray Uid: 2754 Input: 0 Column: 4)
This seems to have been solved for versions 0.8 and 0.9. https://issues.apache.org/jira/browse/PIG-1979
For privacy reasons, I am unable to post the code here. The stack-trace that I get is as follows:

Further notes:
1. I experimented with removing the FOREACH...GENERATE statement where this error seems to be occurring. But then, I get the error message:
ERROR 2270: Logical plan invalid state: duplicate uid in schema
2. When I ran the script with the argument-option `-t ColumnMapKeyPrune`, the script did successfully run albeit very slowly.
