Omkar Vinit Joshi commented on YARN-621:
----------------------------------------
Today everytime filter is getting called twice because we have defined
AuthenticationFilter filtering urls as
* /cluster
* /cluster/*
* /ws
* /ws/*
so if we specify "http://localhost:8088/cluster"; then AuthenticationFilter will
be called twice. However if we request "http://localhost:8088/cluster/cluster";
then it will be called once. We know the related ticket HADOOP-8830 (error due
to AuthenticationFilter getting called twice without request containing
"hadoop.auth" cookie).
Also we can not remove below code because it is required inside
WebApp.serverPathSpecs -> WebApp.configureServlets()
{code} webapp.addServePathSpec(basePath);{code}
Also all these calls will really matter for the first call only. After that
once cookie is set then it doesn't matter. We should definitely fix HADOOP-8830.
