Updating HDInisght configuration files

[kosinsky]

Could these configuration files be updated in the same way as they initially set? For example, if I apply ARM template with modified configuration settings will configuration files be updated?

Is it any way to update these settings via Azure APIs?

@kosinsky Thanks for reaching out with your question. I think that ARM templates are primarily for deploying new resources and not for modifying existing resources.

There may be some limited configuration capabilities through the various APIs, such as the REST API which you could view here: https://docs.microsoft.com/en-us/rest/api/hdinsight/. For all the APIs, check in the Table of Contents under 'Reference'.

For discussion of specific scenarios, you could get some support by emailing the HDInsight discussion alias at: hdidiscuss@microsoft.com. Thanks again.

Thank you @hrasheed-msft.
I'm seeing https://docs.microsoft.com/en-us/rest/api/hdinsight/configurations/update with "Configures the HTTP settings on the specified cluster. This API is deprecated, please use UpdateGatewaySettings in cluster endpoint instead."

Is it correct to assume that we can't update any configuration changes except gateway via Azure REST API?

My scenario is adding support for external metastore HDInsight clusters created via terraform: hashicorp/terraform-provider-azurerm#6145 Just wanted to confirm that it will be oneway only.

@kosinsky I dont have detailed knowledge on that issue. If you reach out to the discussion list, you may find someone who has worked on a similar scenario.
