> 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;
