You can make use of this configuration to do the same.
<property>
<description>List of directories to store localized files in. An
application's localized file directory will be found in:
${yarn.nodemanager.local-dirs}/usercache/${user}/appcache/application_${appid}.
Individual containers' work directories, called container_${contid}, will
be subdirectories of this.

Subject: temporary folders for YARN tasks
When a YARN app and its tasks wants to write temporary files, how does it know
where to write the files?
I am assuming that each task has some temporary space available, and I hope it
is available across multiple disk volumes for parallel performance.
Are those files cleaned up automatically after task exit?
If I want to give lifetime control of the files to an auxiliary service (along
the lines of MR shuffle passing files to the aux service), how would I do that,
and would that entail different file locations?
Thanks
John
