Is it possible to configure ambari for non root user in silent mode.

[#1]

I am trying to automate the process of ambari-server setup and cluster creation. I want to configure ambari-server for non-root user in a silent mode. Please suggest the available options.

Unfortunately it is not possible to setup up ambari to run as 'Non-Root" user in Silent mode.

Please refer to the following section of the Doc: https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.0.0/bk_ambari-installation/content/setup_option...

If you want to run the Ambari Server as non-root, you must run setup in interactive mode. When prompted to customize the ambari-server user account, provide the account information.

Ok.. but was trying to understand if we can modify the property ambari-server.user in the config file /etc/ambari-server/conf/ambari.properties and give appropriate file permission for the logs and config directories.

I am able to modify the property ambari-server.user in the config file /etc/ambari-server/conf/ambari.properties and do a silent ambari setup. ambari-server is started and i am able install the HDP stack, but the installation of the HDP stack components is longer than the expected time.

Ambari does a lots of other things like changing permissions on various directories .....etc apart from just changing the "ambari.properties" property.

Please refer to the following code for more details:

@Jay Kumar SenSharma - Thanks for the detailed info. I tried the interactive ambari-server setup for non root user, even then i found that the hdp cluster creation is taking more time when compared with a cluster with ambari configured for root. Below is a comparison of hdp cluster creation with ambari root and ambari non root.

I had installed the same services on both the clusters.

Note - These clusters were created by following the steps as mentioned in hdp documentation. https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.0.0/bk_ambari-installation/content/ch_Deploy_an...

Cluster creation with ambari configured for root took 21 minutes to install and 15 minutes to start all services.

Cluster creation with ambari configured for non root took 29 minutes to intall and 25 minutes to start all services.

Checked the installation logs, found changeUid.sh script is taking more time in ambari non root cluster creations.

The same is observance while installing and starting all the services.

Looks like ambari with non root user cluster creation does take more time when compared to ambari root user cluster creation...
