fix a copy-and-paste error in log messages
----
> 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 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.
