Data Analytics Studio Installation
Also available as:

Installing the DAS Cluster Components on the Ambari Host

You must install the DAS cluster components (the DAS Webapp and the DAS Event Processor) on the same machine on which you have installed the Ambari server, using an Ambari management pack (MPack). An MPack bundles service definitions, stack definitions, and stack add-on service definitions.

This task must be completed on all the clusters to be used with DAS.
You must have root access to the Ambari Server host node and you must perform this task as a root user.
Download the required repository tarballs from the Hortonworks customer portal by following the instructions provided as part of the product procurement process. The repository tarballs for the DAS Engine are different from the DAS-DP App repository tarballs. You don’t need to download the DAS-DP App repository tarball if you do not choose to use DP.
  1. Log in to the Ambari host on a cluster.
  2. Install the Data Analytics Studio MPack by running the following command:
    ambari-server install-mpack --mpack=<mpack-name> --verbose 
    Replace the <mpack-name> with the name of the MPack. Typically, the format of the MPack is hdpx-data-analytics-studio-mpack-X.X.X.tar.gz.
  3. Restart the Ambari server by entering the following command:
    ambari-server restart
