I think configuration option should be better. Let me rephrase it.

> Allow set hdfs.replication in FlinkYarnSessionCli

> Currently, FlinkYarnSessionCli upload jars into hdfs with default 3 
> replications. From our production experience, we find that 3 replications 
> will block big job (256 containers) to launch, when the HDFS is slow due to 
> big workload for batch pipelines. Thus, we want to make the factor 
> customizable from FlinkYarnSessionCli by adding an option.
