["KWON BYUNGCHANG (JIRA)" <ji...@apache.org>]

KWON BYUNGCHANG created YARN-8741:
-------------------------------------

             Summary: When multiple http filter is configured, RMAuthenticationFilterInitializer does not override
                 Key: YARN-8741
                 URL: https://issues.apache.org/jira/browse/YARN-8741
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: KWON BYUNGCHANG


if security does not enabled and configure hadoop.http.filter.initializers=org.apache.hadoop.http.lib.StaticUserWebFilter,
RMAuthenticationFilterInitializer is appended at that config key by resourcemanager 

RMWebAppUtil.java
{code:java}

   String initializers = conf.get(filterInitializerConfKey);
    if (!UserGroupInformation.isSecurityEnabled()) {
.....

      } else if (initializers.equals(StaticUserWebFilter.class.getName())) {
        conf.set(filterInitializerConfKey,
            RMAuthenticationFilterInitializer.class.getName() + ","
                + initializers);
        conf.set(authTypeKey, "simple");
      }
    }
{code}

hadoop.http.filter.initializers can be configured multiple values and 
when multiple http filters are configured (e.g. YARN-4009),
RMAuthenticationFilterInitializer does not override.
