The issue here is that the iframe that Ambari allows is too small. The bar is hidden because the Search box was moved to a separate line. I don't think you can fix this unless you modify the iframe width under your browser's developer tools. Another option is to simply access the UI via http://sandbox.hortonworks.com:9995/ That way the width of the view is not restricted. More or less this is an issue with Zeppelin+Ambari

I would suggest opening a separate question for getting Spark 2.0.0 If you've been using a different Sandbox you're getting the Remote Host Identification error because the machine that you're running has changed. You can fix this by either entirely removing your ``~/.ssh/known_hosts`` file just removing the entry which pertains to 127.0.0.1 I'm thinking that your Zeppelin issue might be browser compatibility or view related. Have you tried different browsers? Or even just restarting the Sandbox? EDIT: Whoops - Looks like I missed the part where you said you wanted to access both boxes via ssh One option is to add a new entry to /etc/hosts under 127.0.0.1. i.e: sandbox.hortonworks.com 127.0.0.1 # Use for HDP 2.5 SSH will only check hostnames so to get to your 2.4 box: ssh root@127.0.0.1 -p 2222 Then for the 2.5 box you can do: ssh root@sandbox.hortonworks.com -p 2222 Let me know the results

You need to login as the Ambari admin for the services to show up. Use the following tutorial to find instructions on logging in as the admin. http://hortonworks.com/hadoop-tutorial/learning-the-ropes-of-the-hortonworks-sandbox/#setup-ambari-admin-password However the Zeppelin screenshot is odd. In HDP 2.5 Sandbox Zeppelin by default has authentication now. If you seen a login button you can use the following: username: admin password: password1

So after some more investigation and toying around with the API I've found the solution. The first step is to authentic through the API with a POST to /api/login curl -i --data 'userName=admin&password=password1' -X POST http://127.0.0.1:9995/api/login This should return a response like the following: HTTP/1.1 200 OK

The important thing to see here is the Set-Cookie in the response headers. Look for the following: Set-Cookie: JSESSIONID=b1f15e00-4571-4079-a699-338bf619b0c4; Path=/; HttpOnly Using this cookie we can make authorized request to the API by simply setting this as a cookie in the cURL request. curl -i -b 'JSESSIONID=b1f15e00-4571-4079-a699-338bf619b0c4; Path=/; HttpOnly' http://sandbox.hortonworks.com:9995/api/notebook This request should now return a 200 OK response after adding the JSESSIONID cookie. HTTP/1.1 200 OK

After doing a bit of investigating I found that I can make a successful POST to the /api/login which results in a JSON response with a ticket. curl -i --data 'userName=admin&password=password1' -X POST http://sandbox.hortonworks.com:9995/api/login

Is there anything I can do with the ticket to authenticate against a notebook request?

I'm trying to use the Sandbox to perform queries against Zeppelin's Notebook REST API. Previously Zeppelin did not require any credentials to access notebooks. Now that they use authentication I can't seem to find a way to access it. I haven't found any documentation either. I made the following cURL request: curl -i -X GET http://sandbox.hortonworks.com:9995/api/notebook This gives me a redirect with the following response: HTTP/1.1 302 Found

Looks like it's a redirect to /api/login So let's try /api/login and see what happens curl -i -X GET http://sandbox.hortonworks.com:9995/api/login This gives the following response: HTTP/1.1 500 Server Error

I'm currently trying to turn this demo into an Ambari service to start/stop/install the demo services. All of my testing is on the last release of the HDP 2.4 Sandbox https://github.com/vakshorton/DeviceManagerDemo I've turned it into an Ambari service in this fork: https://github.com/ZacBlanco/DeviceManagerDemo My issue I'm having is that the original installation script makes calls to the Ambari API. This in turns triggers tasks such as Start/Stop/Restart of other Ambari services. But when the install script is run by the Ambari Agent, the current task running is the install of DEMOSERVICE. The agent refuses to run the other Ambari tasks that are created by the install script. Thus the script never actually finishes installing because it’s waiting for Ambari to finish the task - which is never does. I have enabled the parallel_execution=1 in /etc/ambari-agent/conf/ambari-agent.ini ( https://issues.apache.org/jira/browse/AMBARI-8189) Is there a way to get Ambari to run the tasks in parallel? Or does anyone know of a workaround for this? The install script is here: https://github.com/ZacBlanco/DeviceManagerDemo/blob/master/package/files/install.sh
