Robert Metzger commented on FLINK-12343:
----------------------------------------
The PR proposes to set {{yarn.file-replication}}, which will set a "global"
replication factor for all files uploaded by the YARN client.
> Allow set file.replication in Yarn Configuration

> 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.
