Zhenhao Li updated YARN-7926:
-----------------------------
Affects Version/s: 3.0.0
> Copy and paste errors in log messages
> -------------------------------------
>
> Key: YARN-7926
> URL: https://issues.apache.org/jira/browse/YARN-7926
> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: Zhenhao Li
> Priority: Minor
> Labels: easyfix
>
> We are a group of researchers from Canada and we are studying refactoring in
> log messages. We found that there are some possible copy and paste errors in
> the log messages, and we think it may cause some confusion when operators are
> reading the log messages.
> The problem is found in the following two methods:
> _org.apache.hadoop.yarn.server.router.webapp.FederationInterceptorREST._*_createNewApplication()_*
>
> and
> _org.apache.hadoop.yarn.server.router.clientrm.FederationClientInterceptor._*_getNewApplication()_*
> These are two very similar methods (possibly code clones) in different
> classes.
> The log messages in *both methods* are:
> _LOG.warn("Unable to_ *_create a new ApplicationId_* _in SubCluster " …);__
> _ _LOG.debug(“_*getNewApplication* try # + … );
> Since one method is getting new application and one method is creating new
> application, we believe that the log messages are incorrectly copied and
> should be changed.
> Please let us know if there is anything that we can further provide you with
> fixing the problem.
