             Summary: Tez should close task if processor fail
                 Key: TEZ-2483
                 URL: https://issues.apache.org/jira/browse/TEZ-2483
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Daniel Dai
             Fix For: 0.7.1


The symptom is if PigProcessor fail, MRInput is not closed. On Windows, this 
creates a problem since Pig client cannot remove the input file.

In general, if a task fail, Tez shall close all input/output handles in 
cleanup. MROutput is closed in MROutput.abort() which Pig invokes explicitly 
right now. Attach a demo patch.
