Hello everyone,
Ambari = 2.7.4
HDP = 3.1.4.0
We need to install Ambari (HDP stack) on our Production Environment running on Ubuntu 16. But the production servers dont have internet access and no ports are open, hence Ambari Install Wizard (Web UI) is not accessible. We used local repository menthod to install ambari server and agents on our cluster. Now the cluster setup and service installation/start up is left which is done via Ambari Web UI installation Wizard.
Recently we came across, Ambari Blueprint that uses REST APIs for cluster deployment. However we are skeptical about the foloowing points:
1) How to specify proper custom configirations for various services ( Hive, Ranger, Kerberos, etc. ) in the json files for the blueprint approach as the propeties are not well documented over the internet.
2) Will we be able to manage the cluster like maintaining HA, Kerberos , Ranger security without their respective wizard.
3) As there wont be any alerts/ warnings as we got from Ambari WebUI, how will the proper monitoring of the production cluster be carried out at any point of time.
4) Maintaing cluster health, Log aggregation, Commission/Decommissioning of nodes, Service additon/ deletion be carried out properly.
5) Will the proper functioning as it is achieved through Ambari WebUI, be achieved through the REST APIs.
Also, is the Blueprint deployment approach recommended for Production environment ( No-Internet access, no port open )?
Please help and thanks in advance!

Hi everyone, Ambari :- 2.7.4 HDP :- 3.1.4.0 I had done the ambari installation using local repositories with no Internet access for Ambari and HDP as mentioned in the official docs by creating directory structure /var/www/html and, untarred all the HDP and Ambari files into /var/www/html/hdp and /var/www/html respectively, as mentioned in the docs. :- [ Ref :- https://docs.cloudera.com/HDPDocuments/Ambari-2.7.5.0/bk_ambari-installation/content/getting_started_setting_up_a_local_repository.html https://docs.cloudera.com/HDPDocuments/Ambari-2.7.5.0/bk_ambari-installation/content/setting_up_a_local_repository_with_no_internet_access.html ] Then, I used python's Simple HTTP Server to host my local repository by running the command `python -m SimpleHTTPServer 2000` from inside /var/www/ instead of using Apache HTTP server as mentioned in the docs, to host my repositories in html directory on port 2000. Installation was done and services are running fine. But the problem that I am facing is the / (root) partition of my system is now at 98% and these files of ambari inside the /var/www/html are taking up 11 GBs. So my question is as the installation is done and the services have been running for few days, is it possible to move all the files inside the /var/www/html into some other directory on my system (lets says /app) and create a directory /app/html and put all those ambari and HDP files inside it and then create a new python SimpleHTTPServer from /app as I did for /var/www/ to host the newly created html directory containing the copied files? What effects will it have, if any and is it safe to do that as my cluster is up and running? Is there any other way is this is not possible? Thanks in advance. Please help! @jsensharma @Shelton @nsabharwal

Hi everyone, I am new to Ambari and have just installed Ambar 2.7.4 with HDP stack 3.1.4 with a cluster having 1 node running the Ambari Server, one being the master node of all service components and there is one more. The installation completed with few warnings, all the services on the web UI are running with green light on. The problem is an alert that says.. SmartSense Bundle Capture Failure Last SamrtSense bundle was not successful. Bundle key.unspecified_xxxxxx_0_2020-10-04_02-00-01, status:failed Also, the Activity Analyzer stops again and again after restarting it. All other services are running. PS: I have just installed this and haven't loaded any data or anything or tested anything. Please provide help! Thankyou! @jsensharma @MattWho @Shelton @nsabharwal
