After you successfully install the DAS MPack through the Ambari console, add the DAS
service through the Ambari UI.
| Note |
---|
If you choose to use a managed Postgres database, then we recommend you to not
install the DAS Webapp on the Ambari host, because there is a possibility that
Ambari would have installed a Postgres database of its own. This can result into a
conflict. However, if you are using a custom Postgres database, then the database
resides on an isolated instance, and there is no chance of a conflict. |
-
Sign in to the Ambari host with your credentials.
http://<ambari-server-host>:8080
-
If you are using a local repository, then specify it in the
dasbn-repo field.
-
Go to and click Show Details.
-
On the Version Details pop-up, click the
Edit Repositories icon.
-
On the Repositories screen, specify the local
repository URL in the dasbn-repo field and click
Save.

In the Ambari Services navigation pane, click .
The Add Service Wizard is displayed.

On the Choose Services page of the Wizard, select

database.
- Set the database host in the Data Analytics Studio
database hostname.
- Set the database username in Data Analytics Studio
database username.
| Note |
---|
The hostname is ignored if the Create Data
Analytics Studio database option is checked, and the
database will be installed on the same host as the
Webapp. |
- Database Password - Enter the password.
You can set the credentials as per your requirement.
-
If Hive SSL is enabled, set the Hive session params in
DAS configuration as follows:

Only admin users have access to all the queries. Non-admin users can
access only their queries. |
