----------------------------------
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.
