Review comment:
The preUploaded Resources means they have been uploaded to hdfs already, not
Yarn public cache.
I have to make clear that Yarn public cache is a type of
`LocalResourceVisibility`. The public cache will be downloaded only once in the
same NodeManager and could be shared by different applications.
