Description:
In this Pig script:
{code}
A = load 'data' as (a:chararray);
B = foreach A { c = UPPER(a); generate ((c eq 'TEST') ? 1 : 0), ((c eq 'DEV') ?
1 : 0); }
{code}
The Eval function UPPER is called twice for each record.
This should be optimized so that the UPPER is called only once for each record
was:
In this Pig script:
{case}
A = load 'data' as (a:chararray);
B = foreach A { c = UPPER(a); generate ((c eq 'TEST') ? 1 : 0), ((c eq 'DEV') ?
1 : 0); }
{case}
