Description

To support avoid issues when a newer JobClient is used with Hadoop versions without MAPREDUCE-7449 the default value of mapreduce.jvm.add-opens-as-default should be false. Currently it's true, this can cause if a newer JobClient is used to submit apps, as the placeholder replacement won't happen during a container launch, resulting in a failed submission.
