[jira] [Created] (HADOOP-10601) We should prevent AuthenticationFilter to be installed twice

Zhijie Shen created HADOOP-10601:
------------------------------------

             Summary: We should prevent AuthenticationFilter to be installed twice
                 Key: HADOOP-10601
                 URL: https://issues.apache.org/jira/browse/HADOOP-10601
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Zhijie Shen


It seems that we have two way to install the authentication filter (at least from YARN aspect):

1. have SPNEGO configs and  use withHttpSpnegoXXXX when starting the web app;
2. add AuthenticationFilterInitializer into the configuration of filter initializer list.

If both ways are used, it seems that two AuthenticationFilter will be instantiated, which is not expected. It's good to allow one or the other.
