> 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()?
