If JVM is already logged in to KDC and has a Subject + TGT in it's security
context it can be used by clients and not logging in again. Example code:
{code:java}
org.apache.hadoop.security.UserGroupInformation.getCurrentUser().doAs(
new java.security.PrivilegedExceptionAction[Unit] {
override def run(): Unit = {
val subject =
javax.security.auth.Subject.getSubject(java.security.AccessController.getContext())
val adminClient = AdminClient.create...
}
)
{code}
