Simple Authentication with Storm 0.10.0

Hi,

I am trying to setup Storm 0.10.0 with security. In the example provided
here https://github.com/apache/storm/blob/v0.10.0-beta/SECURITY.md, the
authentication type is kerberos.

The documentation on AuthenticationFilter suggests that I can also use
simple authentication type.

My question: is the simple type supported in Storm 0.10.0? If so, how
should I configure it?


Here is what I tried. In my storm.yaml, I added this:

 ui.filter:
"org.apache.hadoop.security.authentication.server.AuthenticationFilter"
 ui.filter.params:
   "type": "simple"
   "user.name": "badman"


But when I hit the UI, I get the following exception in ui.log:

2015-11-22 10:28:05.170 o.a.s.s.o.e.j.s.ServletHandler [WARN] Error for
/api/v1/
supervisor/summary
java.lang.NoClassDefFoundError: org/apache/http/client/utils/URLEncodedUtils
        at
org.apache.hadoop.security.authentication.server.PseudoAuthentication
Handler.getUserName(PseudoAuthenticationHandler.java:124)
~[hadoop-auth-2.4.0.ja
r:?]
        at
org.apache.hadoop.security.authentication.server.PseudoAuthentication
Handler.authenticate(PseudoAuthenticationHandler.java:160)
~[hadoop-auth-2.4.0.j
ar:?]


I then downloaded the apache httpclient  (
http://apache.mirror.vexxhost.com//httpcomponents/httpclient/binary/httpcomponents-client-4.5.1-bin.tar.gz)
and unzipped it into the storm lib folder. Now I am getting this exception:


2015-11-22 10:47:37.223 o.a.s.s.o.e.j.s.ServletHandler [WARN]
/api/v1/supervisor/summary
java.lang.NullPointerException

org.apache.http.client.utils.URLEncodedUtils.parse(URLEncodedUtils.java:235)

    at
org.apache.hadoop.security.authentication.server.PseudoAuthenticationHandler.getUserName(PseudoAuthenticationHandler.java:124)
~[hadoop-auth-2.4.0.jar:?]



Any help would be much appreciated.

Sorry. Issue resolved. Looking at the code,
PseudoAuthenticationHandler.java:124, it appears that I have to send
user.name as request parameter.

Thanks,
Max.
