You're completely right, they didn't nominate you to be a guru for nothing.

I'm trying to install Zeppelin using this guide - https://community.hortonworks.com/articles/34424/apache-zeppelin-on-hdp-242.html. However, when I try to add the Zeppelin service using the Ambari dashboard Ambari tries to install the service on one of my slaves, instead of the node where Spark-client is installed. How can I make Ambari install Zeppelin on the client node?

Thanks for the great article. I am running through the instructions, but when I try to add the Zeppelin service in Ambari (step 3) I can't choose any other host but one of my slaves. How can I change it to make Zeppelin be installed on my client host group (where spark-client is installed)?

I think my problem was trying to scale the wrong node group. I was under the impression that the client group was the one used as spark slaves - but found out it was the slaves group doing the heavy lifting. Thanks for the help.

Is there any way I could be informed when this bug is solved? Some kind of newsletter or release notes I can subscribe to?

I have an HDP cluster, and I am trying to scale down some of it's nodes using cloudbreak. The specific group in question was created with 1 node, scaled up to 4 nodes, and now when I try to scale down I manage to scale the group down to 3 nodes but anything smaller than that gives me the following error - `7/25/2016 1:35:07 PM horton-cluster-multi-roles - update failed: New node(s) could not be removed to the cluster. Reason There is not enough node to downscale. Check the replication factor and the ApplicationMaster occupation.` The group host contains only the following components - node_manager, metrics_monitor. So I don't understand how replication factor is a consideration for these nodes.

I used Cloudbreak to scale up one of our node groups, which contained the know_gateway component. When I tried to scale it back down, the action failed because knox_gateway was running on these nodes. Why is it possible to upscale these nodes, but not downscale them? Is there a way around this issue?

Thanks, that sounds like a really nice solution. How do I attach a specific template to a group of the blueprint? I thought I'll find my answers here - http://sequenceiq.com/cloudbreak-docs/latest/configuration/ but couldn't.

Wanted to know if there might be a way to launch a cloudbreak cluster with several aws instance types instead of just a single one. Is there anyway to achieve this?

When trying to create a new cluster using cloudbreak I receive the following error - /cbreak_cloudbreak_1 | 2016-07-19 09:13:12,892 [reactorDispatcher-76] accept:38 INFO c.s.c.s.e.CloudbreakEventHandler - [owner:undefined] [type:CLOUDBREAKEVENTDATA] [id:undefined] [name:undefined] Sending notification with data: CloudbreakEvent{id=58, eventType='CREATE_FAILED', eventTimestamp=Tue Jul 19 09:13:12 UTC 2016, eventMessage='Ambari cluster could not be created.

Is there any way to resolve this?

We have launched a cluster using cloudbreak on AWS, using one of the default templates that come with cloudbreak (minviable-aws) My question is - After the cluster was launched, is there anyway to vertically scale the nodes running on the server? Let's say the template is configured to run m3.large instances, and now I want to add m4.xlarge instances to the cluster (using cloudbreak), is that possible in any way?
