> 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.
