Subject [jira] Created: (PIG-1210) fieldsToRead send the same fields more than once in some cases
Date Fri, 29 Jan 2010 01:31:34 GMT
fieldsToRead send the same fields more than once in some cases
--------------------------------------------------------------

                 Key: PIG-1210
                 URL: https://issues.apache.org/jira/browse/PIG-1210
             Project: Pig
          Issue Type: Bug
    Affects Versions: 0.6.0
            Reporter: Daniel Dai
            Assignee: Daniel Dai
             Fix For: 0.7.0


This bug will happen if the following condition meet:
1. LoadFunc is susceptible to duplicated fields in fieldsToRead. The only LoadFunc we notice
now is Zebra.
2. The first item in FOREACH statement contains reference to the same input more than once.

For example, the following script will be affected:
a = load '11' using org.apache.hadoop.zebra.pig.TableLoader('a0');
b = foreach a generate a0+a0;
