             Summary: We deserialize the entire configuration during vertex 
initialization
                 Key: HIVE-6717
                 URL: https://issues.apache.org/jira/browse/HIVE-6717
             Project: Hive
          Issue Type: Improvement
          Components: Tez
    Affects Versions: 0.14.0
            Reporter: Vikram Dixit K


During the custom vertex initialization, we are deserializing the entire 
configuration. This can be very expensive. The right way to do it would be to 
have a serialized subset of the configuration that is used during 
initialization.
