    Description

      The static keytab and principal for the login user is problematic. The login conf explicitly references these statics. As a result, loginUserFromKeytabAndReturnUGI is unnecessarily synch'ed on the class to swap out the login user's keytab and principal, login, then restore the keytab/principal. This method's synch blocks further de-synching of other methods.
