Update Custom Metadata for existing entities in Cloudera Navigator

[#1]

We are using CDH 5.15 and would like to update the Custom Metadata for the existing entities which can be then seen in Cloudera Navigator. One way is to use Cloudera Navigator console and update but since we have too many of them would like to see if there is other way around to update the custom metadata for all existing entities at once. Any suggestions would be helpful here.

Hi @NickBari ,

Depends on what kind of custom metadata you want to update from Cloudera Navigator, you may consider using the Cloudera Navigator APIs to do this for you.

Documentation and a brief tutorial for the Cloudera Navigator APIs are available on the same node of the cluster that runs the Navigator Metadata Server role:

http://fqdn-n.example.com:port/api-console/tutorial.html

You can refer to below doc for more details:

Thanks and hope this helps!

Thank you @lwang for your response. I went through the documentation and would like to explore the SDK option. I saw that there is link to the github directly, is there any tutorial or video on how SDK can be used to update the Custom Metadata?

Hi @NickBari ,

Have you explored the REST APIs? Majority of times using REST APIs would be able to meet the requirement. navigator-sdk is a public tool and the examples are in github too. For example below code is for incremental extraction of metadata in Java:

Thanks and hope this helps,

Thank you @lwang . Haven't much explored about REST API's but will surely look for. Also will see the navigator sdk in detail.
