# Install the custom service descriptor on the Cloudera Manager server

The Data Optimizer Custom Service Descriptor (CSD) file describes the service to Cloudera Manager (CM). This file is required so that CM is aware of the service and its roles.

1. Copy the CSD file to the `/opt/cloudera/csd/` directory on the Cloudera Manager server.
2. Change the file ownership to the `cloudera-scm` user and group.
   1. `chown cloudera-scm:cloudera-scm`
   2. `/opt/cloudera/csd/pdso-1.3.0.<x>-el7.jar`
3. Change the file permissions to 640: `chmod 640 /opt/cloudera/csd/pdso-1.3.0.<x>-el7.jar`
4. Restart the Cloudera Manager server.

   If you are running the Cloudera Manager Management Service, you must restart it on the Cloudera Manager dashboard.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/pdc-10.2-data-optimizer/pdso-install-landing-page/pdso-install-in-hadoop-cluster/pdso-install-landing-page-hadoop-installation/installing-data-storage-optimizer-on-cloudera-manager-cluster-cp/install-the-custom-service-descriptor-on-the-cloudera-manager-server-pdso-install-in-hadoop.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
