                 URL: https://issues.apache.org/jira/browse/HADOOP-2836
             Project: Hadoop Core
          Issue Type: Improvement
            Reporter: Amir Youssefi


It would be very useful if we provide exact location (Part file and Offset) of 
an input data-set which creates an error. 

Root cause could be various issues e.g. corrupt record, incorrect number of 
fields assumed by user, not escaping field separator, incorrect data 
type/length assumption etc. but having exact location of input data-set 
creating error is helpful.
