Hi,

I just got a Cloudbreak 2.7.1 deployer server running. The press release for HDP 3.0 mentioned that is was possible to deploy 3.0 using Cloudbreak but HDP 3.0 isn't an available option under 2.7.1 (HDP 2.6 only). Do I need to upgrade Cloudbreak, add an MPack or how should I deploy HDP 3.0 via Cloudbreak?

Paul,

I ran into the same issue with CB 2.7.1. I'm sure there must be a better way to get it resolved, but here are the steps I used to create an HDP3.0 blueprint first, then further create an HDP 3.0 cluster by using CB 2.7.1:

Step1: Click 'Blueprints' on the left navigation pane, then click 'CREATE BLUEPRINT', input the name, for instance 'HDP 3.0 - Data Science: Apache Spark 2, Apache Zeppelin'

Step2: Add the following JSON into the 'Text' field, and click 'CREATE'

{
  "Blueprints": {

Step3: You now should be able to see the newly added HDP3.0 blueprint, and create a cluster off it

Hope it helps!

If you found it resolved the issue, please "accept" the answer, thanks.

@Dominika Bialek : Hello Dominika, another interesting thing I found out - if I change the stack version to 3.1 in your HDP3.0 blueprint to try to create HDP3.1 cluster, it fails with the following error (but runs well with 3.0) -

Couldn't determine Ambari repo for the stack: <blueprint-name>

Change made:

"Blueprints":{

"blueprint_name":"hdp31-data-science-spark2-v4",

"stack_name":"HDP",

"stack_version":"3.1"

},

So, does it mean the latest Cloudbreak version (2.7.x) can support HDP3.0 but not HDP3.1?

Another follow up question:

When you said "the plan was to only ship EDW-Analytics with HDP 3.x", does it mean the customization of blueprint will not be possible in the current Cloudbreak version to include other components that come with EDW-ETL?

Please advise.

@Pushpak Nandi

Cloudbreak 2.7.2 or earlier does not fully support HDP 3.x. That's why no default HD 3.x blueprints were included. This doesn't mean that it is impossible to create some HDP 3.x cluster; it just means that there was no sufficient testing completed and/or that no changes were made in Cloudbreak/Ambari for Cloudbreak to support it. A future Cloudbreak release will support some HDP 3.x release(s).

Regarding the second question, what I meant to say is that there is always a limited number of blueprints provided by default; You can always create your own. If we do not ship one for EDW-ETL then you can prepare one by yourself snd upload it.

Hope this helps!

Hi @Dominika Bialek, few queries:

1. Can you please supply a custom blueprint for

Data Science: Apache Spark 2, Apache Zeppelin/EDW-Analytics with HDP 3.1?

2. Also, if I use the custom blueprint (Data Science: Apache Spark 2, Apache Zeppelin with HDP3.0) supplied by you in this thread and try to create a 3 node cluster, there is a timeout happening due to which cluster creation is failing every time (this is not happening with HDP2.6 default blueprint).

Operation timed out. Failed to find all '3' Ambari hosts. Stack: '34' 2/6/2019, 4:24:20 PM

Can you please advise?

@Pushpak Nand

Perhaps you want to try Cloudbreak 2.9 if launching HDP 3.1 is important to you:

https://community.hortonworks.com/articles/239903/introducing-cloudbreak-290-ga.html

https://docs.hortonworks.com/HDPDocuments/Cloudbreak/Cloudbreak-2.9.0/index.html

You can update to it if you are currently on an earlier release. It does come with default HDP 3.1 blueprints.
