Rajesh Balamohan commented on TEZ-4254:
---------------------------------------
Had offline conversation with [~mustafaiman] . If config has something like
"tez.runtime.shuffle.ssl.enable=${mapreduce.shuffle.ssl.enabled}" (ie via
references), then it can lead to issue when we unset in config.
> Don't unset the tez config if both mr and tez config have same value.

> while translated mr config to the tez config we unset config here.

> 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
