             Summary: Optimize the number of FS calls to get schema to cut down time before job launch
                 Key: PIG-3204
                 URL: https://issues.apache.org/jira/browse/PIG-3204
             Project: Pig
          Issue Type: Improvement
            Reporter: Rohini Palaniswamy


  Currently there are a lot of NN calls made to determine if there is a schema file for a path in a LOAD statement. When there is a slow NN(caused by whole bunch of other issues), it takes a lot of time for this and we found the scripts spending anywhere from 5 mins to 40 mins depending upon the script. It seems to be a good place for optimization.
