-----------------------------------

             Summary: Don't unset the tez config if both mr and tez config have 
same value.
                 Key: TEZ-4254
                 URL: https://issues.apache.org/jira/browse/TEZ-4254
             Project: Apache Tez
          Issue Type: Bug
    Affects Versions: 0.9.1
            Reporter: Rajkumar Singh


while translated mr config to the tez config we unset config here.
https://github.com/apache/tez/blob/master/tez-mapreduce/src/main/java/org/apache/tez/mapreduce/hadoop/MRHelpers.java#L187

There is no need to unset the config if both mr and tez have same value.

we observed if equivalent of tez config for mapreduce.shuffle.ssl.enabled 
(tez.runtime.shuffle.ssl.enable) set to true, we unset the config, this 
propagate config tez.runtime.shuffle.ssl.enable={mapreduce.shuffle.ssl.enabled} 
at runtime and variable substitution does not work correctly in the absence of 
mrconfig runtime.
