Knox Gateway

[#1]

Hello

I have knox installed in my HDP cluster. I am not sure how i can configure it. I want to secure the web requests sent to services like webhdfs and ranger.

i have included this in my topology but im not sure how i can use the gateway or what other configurations are missing

<service>

<role>WEBHDFS</role>

<url>https://[HOSTNAME]:50470/webhdfs</url>

</service>

[#2]

you can access webhdfs using this url :

https://{gateway-host}:{gateway-port}/{gateway-path}/{cluster-name}/webhdfs

for more info you can refer to https://knox.apache.org/books/knox-0-4-0/knox-0-4-0.html#WebHDFS

and are you facing any issue after changing the topology you mentioned in your question ?

[#3]

HTTP ERROR: 404

Problem accessing /gateway/HDPBei/webhdfs. Reason:

    Not Found

this is the full URL i used

https://hostname:8443/gateway/cluster-name/webhdfs/data/v1/{Directory path}?op=ListStatus

[#5]

I have fixed the gateway path in the URL and now it is asking for a username and password. which account would it be asking for?

[#6]

can you try something like guest:guest-password or admin:admin-password ?

[#7]

I also want to know the username and password

[#8]

i don't know the mean about gateway-path and cluster-name

[#9]

gateway-path is defined in conf/gateway-site.xml (gateway.path property), and cluster-name is actually the name of the Knox topology (name of the topology.xml file).

The default knox.path property value is gateway, and if the topology file is named mytopology.xml, the cluster-name is mytopology.

So, putting them together:

http://hostname:8443/gateway/mytopology/webhdfs/v1/?op=LISTSTATUS

I would like to know how to see the knox page but I have been prompted after the input url: unable to visit this site hope you can help me
