             Summary: Move the fetch code for local disk fetch from data movement event handlers to fetcher
                 Key: TEZ-1446
                 URL: https://issues.apache.org/jira/browse/TEZ-1446
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Prakash Ramachandran
            Assignee: Prakash Ramachandran


doing the fetch in the EventHandler has the drawback of tying up the EventHandling thread, in case it takes time to read the Index file. Even, for a healthy disk - we can do without any delays on this thread, so that the fetcher have some work to do.  
Also Need to add Unit test cases for the local fetch.
