If you installed DPS on a new cluster, you can install the service engine using the
Install Wizard process. If using existing clusters, see the instructions for configuring the
DLM Engine on existing clusters.
- You must have root access to the Ambari Server host node to perform this task.
- This task must be completed on all clusters to be used with DLM.
- See the DPS Support Matrices for information about Apache components
required for the DPS services you are installing.
-
Launch Ambari in a browser and log in.
http://
<ambari-server-host>:8080
- Default credentials are shown below.
- Username: admin
- Password: admin
-
From the Ambari Welcome page, choose Launch Install Wizard and begin the wizard.
- On the Select Versions page, change the Base URL
path for each DPS service to point to the local repository, for example:
http://webserver.com/DLM/centos7/1.1.0.0
URLs shown above are for example purposes only. Actual URLs might be
different.
- On the Select Services page of the Install Wizard, select the engine or
agent you want to configure, and then follow the on-screen instructions.
Other required services are automatically selected.
- When prompted to confirm addition of dependent services, give a positive confirmation to all.
This adds other required services.
-
On the Assign Masters page, you can choose the default
settings.
-
On the Customize Services page, fill out all the required
username and password fields that are highlighted.
You can set credentials to whatever you want, such as admin/admin.
-
If doing Hive replication with DLM, from the Customize
Services page, enable Hive replication.
-
Click Hive in the list of services.
-
On the Settings tab, move the toggle to *off* for "Run
as end user instead of Hive user".
-
Click HDFS in the list of services.
-
Scroll to the Custom core-site section and modify the
following parameter:
hadoop.proxyuser.hive.hosts=*
- If using DSS, configure the DataPlane Profiler.
-
In the Services pane, click DataPlane Profiler.
-
Click Configs>Advanced, and
then scroll to Custom core-site.
-
Click Add Property and enter the following key-value
pairs:
hadoop.proxyuser.livy.groups=*
hadoop.proxyuser.livy.hosts=*
-
Complete the remaining installation wizard steps and close the wizard.
- Ensure that all components required for your DPS services have started successfully.
See the DPS support requirements for information about required Apache
components.
-
Repeat this procedure on the Ambari hosts on all remaining clusters, for each DPS
service engine and agent you installed.
