Kostas Kloudas commented on FLINK-17515:
----------------------------------------
Thanks for the comment [~felixzheng] .
The code that I am refactoring makes certain assumptions that may not be valid
for Kubernetes. For example it registers files as local resource
(yarn-specific) and it makes use of the Hadoop Filesystem abstraction. The
purpose of this PR is simply to start cleaning up a bit the code in the
{{YarnClusterDescriptor}} (although it is a small step). It does not introduce
any new code or functionality.
If we want to make these things more abstract then I think we should come up
with a design.

> Currently the file uploading functionality when deploying on Yarn is spread
> across the {{YarnClusterDescriptor}} and the {{org.apache.flink.yarn.Utils}}.

> the {{YarnApplicationFileUploader}}.
> This issue does not add/remove/change any of the existing functionality.
