[jira] [Created] (PIG-2864) LOAD with FILTER should read data without MapReduce

Bill Graham created PIG-2864:
--------------------------------

             Summary: LOAD with FILTER should read data without MapReduce
                 Key: PIG-2864
                 URL: https://issues.apache.org/jira/browse/PIG-2864
             Project: Pig
          Issue Type: Improvement
            Reporter: Bill Graham


A script like this should be able to read data directly from the LoadFunc and serve it without kicking off a MapReduce job:
{noformat}
a = LOAD 'data.txt';
b = LIMIT 10;
DUMP b;
{noformat}

Hive has similar functionality which is handy.
