Wangda Tan commented on YARN-8714:
----------------------------------

[~tangzhankun] , I'm still not quite sure about:
{code:java}
/opt/script2.py->script2.py{code}
Does it mean the /opt/script.2 on the NM machine or Submarine will upload the 
local file /opt/script2.py to HDFS staging area first and localize to script2?

Regarding to the local file name "{{->dest}}", I think this is a bit confusing 
to me, instead, should we use ":" instead? 

Also, do you think should Submarine support upload local file to HDFS staging 
first and then localize to local folder?

> [Submarine] Support files/tarballs to be localized for a training job.
