Review request for pig and thejas.
Summary
-------
The following script produce wrong result:
data = LOAD 'data.txt' using PigStorage() as (referrer:chararray,
canonical_url:chararray, ip:chararray);
best_url = FOREACH data GENERATE ((canonical_url != '' and canonical_url is not
null) ? canonical_url : referrer) AS url, ip;
filtered = FILTER best_url BY url == 'badsite.com';
dump filtered;
data.txt:
badsite.com 127.0.0.1
goodsite.com/1?foo=true goodsite.com 127.0.0.1
Expected:
(badsite.com,127.0.0.1)
We get nothing.
This addresses bug PIG-1935.
