[jira] [Created] (TEZ-1371) Avoid re-sending TaskContext more than once to the same node

Bikas Saha created TEZ-1371:
-------------------------------

             Summary: Avoid re-sending TaskContext more than once to the same node
                 Key: TEZ-1371
                 URL: https://issues.apache.org/jira/browse/TEZ-1371
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Bikas Saha


Once a TaskContext has been sent to a machine then the other tasks with the same context can use the fetched TaskContext. The same container can re-use the TaskContext cached in memory from a previous run of the same task. A hash/checksum of the TaskContext could be used to identify identical task contexts that do not need to be fetched.
