Zac Zhou created YARN-8725:
------------------------------
Summary: Submarine job staging directory has a lot of useless
PRIMARY_WORKER-launch-script-***.sh scripts when submitting a job multiple
times
Key: YARN-8725
URL: https://issues.apache.org/jira/browse/YARN-8725
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Zac Zhou
Assignee: Zac Zhou
Submarine jobs upload core-site.xml, hdfs-site.xml, job.info and
PRIMARY_WORKER-launch-script****.sh to staging dir.
core-site.xml, hdfs-site.xml and job.info would be overwritten if a job is
submitted multiple times.
But PRIMARY_WORKER-launch-script****.sh would not be overwritten, as it has
random numbers in its name.
The files in the staging dir is as follows：

We should stop the staging dir from growing or have a way to clean it up
