Connecting oracle database using spark with Kerberos authentication?

问题

My jdbc is connected to oracle database using krb5loginmodule without any issue, by giving keytab file or ticket cache.But, due to performance, I want to connect my oracle database using Spark. If I use simple username and password, I am able to connect my spark application to Oracle database using below snippet:

Dataset<Row> empDF = sparkSession.read().format("jdbc")
            .option("url", "jdbc:oracle:thin:hr/1234@//127.0.0.1:1522/orcl")
            .option("dbtable", "hr.employees")
            //.option("user", "hr")
            //.option("password", "1234")
            .option("driver", "oracle.jdbc.driver.OracleDriver")
            .load();
empDF.printSchema();
empDF.show();

Now, how can I enable Kerberos authentication using keytab, instead of using a hardcoded username and password? I don't want to use a ticket cache by manually doing kinit.
