What would you like to be improved?

I have flink, hive hadoop cluster with kerberos, and want to use kyuubi access flink sql using yarn-session mode
so i get some error:
kyuubi-flink-sql-engine.log
kyuubi-server-hadoop98.test.com.log

I found this guide: https://kyuubi.readthedocs.io/en/master/deployment/engine_on_yarn.html#deploy-kyuubi-flink-engine-on-yarn

Deploy Kyuubi Flink Engine on YARN，YARN Session Mode，Kerberos
With regard to YARN session mode, security.kerberos.login.keytab and security.kerberos.login.principal are not effective, as Kyuubi Flink SQL engine mainly relies on Flink SQL client which currently does not support

so, Are there any plans for Kyuubi Flink Engine on YARN to support Kerberos?

How should we improve?

I don't know.

Maybe:
kyuubi/kyuubi-server/src/main/scala/org/apache/kyuubi/client/KyuubiSyncThriftClient.scala add some method like getPlainTransport() and support SASL. i am not sure

Are you willing to submit PR?
