Marcelo Vanzin updated SPARK-3979:
----------------------------------
Description:
This code in ClientBase.scala sets the replication used for files uploaded to
HDFS:
{code}
val replication = sparkConf.getInt("spark.yarn.submit.file.replication",
3).toShort
{code}
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").
