attilapiros opened a new pull request, #38048: URL: https://github.com/apache/spark/pull/38048
### What changes were proposed in this pull request? When the delegation token is fetched at the first time (see the `fetchDelegationTokens()` call at `HadoopFSDelegationTokenProvider#getTokenRenewalInterval()`) the principal is the current user but at the subsequent token renewals (see `obtainDelegationTokens()` where `getTokenRenewer()` is used to identify the principal) are using a Hadoop/Yarn specific principal even on resource managers different from YARN. ### Why are the changes needed? To avoid `org.apache.hadoop.security.AccessControlException: Permission denied.` for long running applications. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested?
