Installing Data Analytics Studio
Installing DAS is a three-step process. First, you install the DAS cluster components on the
Ambari server using the MPacks. Then you add the DAS service through the Ambari UI. Lastly, you
install the DAS DP App on the DP environment.
Installing the DAS Cluster Components on the Ambari Host You must install 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. Adding the DAS Service through the Ambari UI After you successfully install the DAS MPack through the Ambari console, add the DAS service through the Ambari UI. Configuring DAS for Knox SSO To enable DAS to work with the HDP cluster SSO, configure the Knox settings as described in this topic. (Optional) Configuring DAS for SSL/TLS If your HDP cluster is SSL enabled, then you can configure SSL. You can use one of the two options to set up SSL certificates. Setting up the tmp Directory DAS allows you to download logs for secure clusters. To download logs, make sure that the DAS service user has write permission to the /tmp directory. Also make sure that the /tmp directory has sufficient storage space to hold logs from a query for the download logs feature to work.
