Summary: Improve
existsApplicationHomeSubCluster/existsReservationHomeSubCluster Log Level
Key: YARN-11516
URL: https://issues.apache.org/jira/browse/YARN-11516
Project: Hadoop YARN
Issue Type: Improvement
Components: federation, router
Affects Versions: 3.4.0
Reporter: Shilun Fan
Assignee: Shilun Fan
The method FederationStateStoreFacade#existsApplicationHomeSubCluster is used
to determine whether an application has a HomeSubCluster assigned. If the
HomeSubCluster is not found, we currently log a warning message. However,
during the first submission of an application, it is normal for the
corresponding HomeSubCluster not to exist. This warning message might mislead
users into thinking that an exception occurred. To address this, we should
change the logging format of this message to "debug".
FederationStateStoreFacade#existsReservationHomeSubCluster also needs to change
the log level for the same reason.
