Xun Liu commented on YARN-8714:
-------------------------------

# Support files and folders
 # HDFS type and local file type supporting HDFS:// prefix at the same time
 # Keep it intact: the uploaded package is compressed, and the submarine is 
automatically decompressed into the container, which is not suitable, because 
if I rush to save the file that needs to upload the compressed package format, 
it will be destroyed. And it also introduces ambiguity.
 # Parameter format: {color:#FF0000}--localizations hdfs:///user/yarn->.{color} 
# indicates the current execution path of the container
 # Parameter format: {color:#FF0000}--localizations 
hdfs:///user/yarn->./abc{color} # Indicates the abc folder under the current 
execution path of the container (submarine marks the file under 
hdfs:///user/yarn as an abc .tar.gz compression package, extract the abc folder 
when pulling up the container, then mount it in it)

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