Re: Deploy Schema Registry as an HA Setup

[Saravanan Raju]

Hi,

To run in HA mode you need to spin two nodes in your case and point them to the same database. All the nodes talk to the same database will function in HA.

Thanks

I need to deploy Schema Registry in two nodes. Therefore we need to use an HA setup for this. Can I get some support or relevant documents for that?

Thanks a lot for your help.

Hi Saravanan,

Thanks for your reply. I tried it using the same way as you have mentioned. It works fine. I was able to figure out how it works with backend using the API calls. But, just to clarify, how it handles in the frontend? In addition, is there any mechanism to add a custom authentication with the schema registry?

[Satish Duggana]

You can explore adding a filter in webapp for any custom authentication (like SPNEGO filter added for Kerberos).

 

Thanks,

Satish.

Following up on Satish's recommendation for custom authentication you can take a look at https://github.com/hortonworks/registry/blob/master/common-auth/src/main/java/com/hortonworks/registries/auth/server/JWTAuthenticationHandler.java

It expects a JWT set in the request. If it does not find it it will direct to a url which can perform form based authentication or any other custom mechanism. As long as that custom authentication url sets a valid JWT as a cookie, it should work.
