             Summary: HS2: SASL auth loads HiveConf
                 Key: HIVE-18905
                 URL: https://issues.apache.org/jira/browse/HIVE-18905
             Project: Hive
          Issue Type: Bug
            Reporter: Gopal V


SASL authentication filter does a new HiveConf() for no good reason.

{code}
  public static PasswdAuthenticationProvider getAuthenticationProvider(AuthMethods authMethod)
    throws AuthenticationException {
    return getAuthenticationProvider(authMethod, new HiveConf());
  }
{code}

The session HiveConf is not needed to do this operation & it can't be changed after the HS2 starts up (today).
