Perhaps debug logging would be helpful. Can you set the log level to debug, and see if anything useful appears in gateway.log?

Do you see any messages in gateway.log about a whitelist?

So, you're able to access the Knox UI via the public IP, but login is failing? Can you see anything relevant in the Knox logs? Is Knox SSO in play here? What do you mean by this? "the topologies created from knox UI is throwing 404 error."

@abbas mohammadnejad You have to explicitly set the gateway.dispatch.whitelist property in gateway-site.xml, such that the pattern will match the endpoint address.

It looks like you're missing the gateway path segment in the actual command: 'https://10.224.155.25:9443/Vamshi/webhdfs/v1/?op=LISTSTATUS' should be 'https://10.224.155.25:9443/gateway/Vamshi/webhdfs/v1/?op=LISTSTATUS' And have you intentionally configured the gateway port to 9443 (vs the default 8443)?

Is your sandbox topology pointing to your cluster correctly? What does your gateway-audit.log show?

Have you considered using the Ambari REST API, or are you concerned with clusters which are not managed by Ambari? You could use curl to invoke it from your scripts.

Thank you for following up. That's what I suspected, and it's good to document it here for future reference.

@Lian Jiang Can you explain why the default whitelist was not working for your deployment?

pzampino · ‎08-22-2018

None of Ambari, Zeppelin, or RangerUI are affected by this whitelisting. Can you see the default whitelist in gateway.log? It should say something like Applying a derived dispatch whitelist because none is configured in gateway-site: xxxxxxx
