Tutorial Issue: Can't connect to HDFS through the Knox Gateway

[#1]

I'm running though "Securing your Hadoop Infrastructure with Apache Knox." I've installed HDP 2.3 and have been following the steps described. I can run step 6, accessing the Hadoop Cluster via WebHDFS. But step 7, accessing the Hadopp Cluster via the Apache Know Gateway fails.

curl -iku guest:guest-password -X GET 'https://localhost:8443/gateway/sandbox/webhdfs/v1/?op=LISTSTATUS'

HTTP/1.1 404 Not Found Cache-Control: must-revalidate,no-cache,no-store Content-Type: text/html;charset=ISO-8859-1 Content-Length: 1294 Server: Jetty(8.1.14.v20131031) <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"/> <title>Error 404 Not Found</title> </head> <body> <h2>HTTP ERROR: 404</h2> <p>Problem accessing /gateway/sandbox/webhdfs/v1/. Reason: <pre> Not Found</pre></p> <hr /><i><small>Powered by Jetty://</small></i> </body> </html>

All the requisite processes seem to be running. I have no clue what to look at to get this working.

Thank you both for your help. I restarted the Knox LDAP manually instead of with Ambari and used the default path instead of sandbox. I can get connected now.

Need to start Demo LDAP from service actions in order to test the test accounts with out LDAP integration
