[jira] [Created] (IMPALA-8154) Disable auth_to_local by default

Michael Ho created IMPALA-8154:
----------------------------------

             Summary: Disable auth_to_local by default
                 Key: IMPALA-8154
                 URL: https://issues.apache.org/jira/browse/IMPALA-8154
             Project: IMPALA
          Issue Type: Bug
          Components: Distributed Exec
    Affects Versions: Impala 3.1.0, Impala 2.12.0
            Reporter: Michael Ho
            Assignee: Michael Ho


Before KRPC the local name mapping was done from the principal name entirely, however when KRPC is enabled Impala starts to use the system auth_to_local rules, "use_system_auth_to_local" is enabled by default. This can cause regression in cases where localauth is configured in the krb5.conf. This may cause issue for connection between Impalad after [this commit|https://github.com/apache/impala/commit/5c541b960491ba91533712144599fb3b6d99521d]

The fix is to disable use_system_auth_to_local by default.
