Forgot to mention that I am using spark-submit to submit jobs, and a verbose
mode print out looks like this with the SparkPi examples.The .sparkStaging
won't be deleted. My thoughts is that this should be part of the staging and
should be cleaned up as well when sc gets terminated.

Subject: HDFS folder .sparkStaging not deleted and filled up HDFS in yarn mode
Date: Wed, 18 Jun 2014 11:05:12 -0700
Hi All,
Have anyone ran into the same problem? By looking at the source code in
official release (rc11),this property settings is set to false by default,
however, I'm seeing the .sparkStaging folder remains on the HDFS and causing it
to fill up the disk pretty fast since SparkContext deploys the fat JAR file
(~115MB) every time for each job and it is not cleaned up.
yarn/stable/src/main/scala/org/apache/spark/deploy/yarn/ApplicationMaster.scala:
val preserveFiles = sparkConf.get("spark.yarn.preserve.staging.files",
"false").toBoolean

Is this something that needs to be explicitly set in
:SPARK_YARN_USER_ENV="spark.yarn.preserve.staging.files=false"
http://spark.apache.org/docs/latest/running-on-yarn.htmlspark.yarn.preserve.staging.filesfalseSet
to true to preserve the staged files (Spark jar, app jar, distributed cache
files) at the end of the job rather then delete them.or this is a bug that is
not honoring the default value and is override to true somewhere?
Thanks.
