manuzhang opened a new pull request, #36658: URL: https://github.com/apache/spark/pull/36658
### What changes were proposed in this pull request? Change precedence of alternative configs of Hadoop Filesystems to access (`spark.kerberos.access.hadoopFileSystems`). ### Why are the changes needed? Before https://github.com/apache/spark/pull/23698, the precedence of configuring Hadoop Filesystems to access is ``` spark.yarn.access.hadoopFileSystems -> spark.yarn.access.namenodes ``` Afterwards, it's ``` spark.kerberos.access.hadoopFileSystems -> spark.yarn.access.namenodes -> spark.yarn.access.hadoopFileSystems ``` When both `spark.yarn.access.hadoopFileSystems` and `spark.yarn.access.namenodes` are configured with different values, the PR will break backward compatibility and cause application failure. ### Does this PR introduce _any_ user-facing change? Yes. Fix backward compatibility. ### How was this patch tested? Updated UT. -- This is an automated message from the Apache Git Service.
