Github user themodernlife commented on the issue:
https://github.com/apache/spark/pull/17530
There is a spot in HadoopFSCredentialProvider where it looks for a Hadoop
config key related to yarn to set the token renewer.
In getTokenRenewer it calls Master.getMasterPrincipal(conf) which will need
some yarn configuration set for things to succeed.
Right now the PR doesn't set that, so it needs to be set under the user's
HADOOP_CONF even though it had no real effect. That probably should be changed.
Didn't have a chance to dig into the ticket you linked to but will try to
have a look and compare notes. If anything comes to mind will comment there.
