mateczagany opened a new pull request, #21788:
URL: https://github.com/apache/flink/pull/21788
## What is the purpose of the change
Hadoop versions starting from 3.3.2 have reworked copying local files to
remote using S3AFileSystem. Now it requires the passed local Hadoop Path to
have a `scheme` specified.
## Brief change log
YarnApplicationFileUploader will append `file://` scheme for local path if
none specified
## Verifying this change
I manually tested on a local single-node Hadoop 3.3.4 cluster with
`fs.defaultFS` pointing to a local Minio S3 server. Creating a Flink YARN
session failed before the fix, but worked after.
Also added new unit test in `YarnApplicationFileUploaderTest`.
