> For environments with non-standard location of krb5.conf, most native kerberos implementations
support KRB5_CONFIG environment variable specifying the location. Java doesn't recognize this
environment variable, but supports java.security.krb5.conf system property for the same.
> Since environment variables can be accessed in Java, Spark should include the system
property on the command-line while the launcher command-line is built and add support for
custom krb5.conf location and make this seamless. This variable can then go into the spark-env.sh.
