> PROBLEM: Authenticating to HS2 in HTTP mode with Kerberos, auth_to_local 
> mappings do not get applied.  Because of this various permissions checks 
> which rely on the local cluster name for a user are going to fail.
> STEPS TO REPRODUCE:
> 1.  Create  kerberos cluster  and HS2 in HTTP mode
> 2.  Create a new user, test, along with a kerberos principal for this user
> 3.  Create a separate principal, mapped-test
> 4.  Create an auth_to_local rule to make sure that mapped-test is mapped to 
> test
> 5.  As the test user, connect to HS2 with beeline and create a simple table:
> {code}
> CREATE TABLE permtest (field1 int);
> {code}
> There is no need to load anything into this table.
> 6.  Establish that it works as the test user:
> {code}
> show create table permtest;
> {code}
> 7.  Drop the test identity and become mapped-test
> 8.  Re-connect to HS2 with beeline, re-run the above command:
> {code}
> show create table permtest;
> {code}
> You will find that when this is done in HTTP mode, you will get an HDFS error 
> (because of StorageBasedAuthorization doing a HDFS permissions check) and the 
> user will be mapped-test and NOT test as it should be.
> ANALYSIS:  This appears to be HTTP specific and the problem seems to come in 
> {{ThriftHttpServlet$HttpKerberosServerAction.getPrincipalWithoutRealmAndHost()}}:
> {code}
>       try {
>         fullKerberosName = 
> ShimLoader.getHadoopShims().getKerberosNameShim(fullPrincipal);
>       } catch (IOException e) {
>         throw new HttpAuthenticationException(e);
>       }
>       return fullKerberosName.getServiceName();
> {code}
> getServiceName applies no auth_to_local rules.  Seems like maybe this should 
> be getShortName()?
