> Currently, we pass jars using --jars option while submitting spark job. Also, we add spark.yarn.dist.files option in case of yarn-client mode. 
> Instead of that, we can have only --files option and pass on the files which are present in mapreduce.job.cache.files. While doing so, we make sure that spark won't make another copy of the files if files exist on the hdfs. We saw the issues when files are getting copied multiple times and causing exceptions such as :

> Diagnostics: Resource hdfs://localhost/user/saley/.sparkStaging/application_1234_123/oozie-examples.jar changed on src filesystem
> {code}
