[jira] [Created] (HADOOP-10703) Duplicate filter instances are created during HttpServer2 initialization

Benoy Antony created HADOOP-10703:
-------------------------------------

             Summary: Duplicate filter instances are created during HttpServer2 initialization
                 Key: HADOOP-10703
                 URL: https://issues.apache.org/jira/browse/HADOOP-10703
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
    Affects Versions: 2.4.0
            Reporter: Benoy Antony
            Assignee: Benoy Antony


The HttpServer2.defineFilter creates a Filter instance for each context. By default, there are 3 contexts.
So there will be 3 separate AuthenticationFilter instances and corresponding AuthenticationHandler instances. This also results in 3 separate initializations of AuthenticationHandler.
The log file illustrating this repeated initialization is attached.
