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

org.apache.hadoop.security.authentication.server.PseudoAuthentication

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]

Any help would be much appreciated.
