             Summary: Pig pushes matches operator to HCatLoader causing script to fail
                 Key: PIG-4482
                 URL: https://issues.apache.org/jira/browse/PIG-4482
             Project: Pig
          Issue Type: Bug
    Affects Versions: 0.12.0
            Reporter: Rohini Palaniswamy


HCatLoader fails with as it cannot understand the matches operator. Even if we don't push down, specifying regular expression in partition key will be bad for performance as it will scan the whole table. Need to see if hcat can indeed support basic wildcard regular expression and translate it to LIKE clause in database query.
