Arun Suresh commented on HADOOP-10709:
--------------------------------------
[~benoyantony],
The {{HttpServer2#build()}} method also calls the {{server.initSpnego()}}
method which inturn also adds an *authentication* filter via the
{{defineFilter()}} method. I think you might need to do the
{{!HttpServer2.filterExists(name)}} check there too..
Also, in the {{HttpServer2#initializeWebServer()}} method as well :
{noformat}
final FilterInitializer[] initializers = getFilterInitializers(conf);
if (initializers != null) {
conf = new Configuration(conf);
conf.set(BIND_ADDRESS, hostName);
for (FilterInitializer c : initializers) {
c.initFilter(this, conf);
}
}
{noformat}
Do we need to do the check there as well ?

> Currently, we need to define separate authentication filters for webhdfs and
> general webui. This also involves defining parameters for those filters.
> It will be better if one could reuse filters for web apps if desired.
