   I think we can set the hdfs.replication in YarnConfiguration of 
AbstractYarnClusterDescriptor. As, this configuration is only used in client 
side, so will not impact the runtime file replications. The reason I initially 
choose to use the setReplication method is that our org will use S3 for long 
term to submit job to different cluster management system. It looks 
S3AFileSystem doesn't implement the method. I think it is good to use 
hdfs.replication initially. How do you think?
