BTW, this would avoid issues like this:

 Yarn backend's default file replication should match HDFS's default one

 Key: SPARK-3979
 URL: https://issues.apache.org/jira/browse/SPARK-3979
 Project: Spark
  Issue Type: Bug
  Components: YARN
Reporter: Marcelo Vanzin
Priority: Minor

 This code in ClientBase.scala sets the replication used for files uploaded to 
 HDFS:
 {{noformat}}
 val replication = sparkConf.getInt(spark.yarn.submit.file.replication, 
 3).toShort
 {{noformat}}
 Instead of a hardcoded 3 (which is the default value for HDFS), it should 
 be using the default value from the HDFS conf (dfs.replication).
