Unity exporter support for Azure

[N-o-Z]

Error:

Error: runtime error: lakefs/catalogexport/unity_exporter.lua:54: external table "prm_maestro_cliente_gt" creation failed: FAILED: BAD_REQUEST [UC_FILE_SCHEME_FOR_TABLE_CREATION_NOT_SUPPORTED] Creating table in Unity Catalog with file scheme https is not supported.
Instead, please create a federated data source connection using the CREATE CONNECTION command for the same table provider, then create a catalog based on the connection with a CREATE FOREIGN CATALOG command to reference the tables therein.

Trying to create an external location in databricks using https scheme results in the following error:

ErrorClass=INVALID_PARAMETER_VALUE.UNSUPPORTED_LOCATION_SCHEME] url has invalid URI scheme https. Valid URI schemes include s3, gs, s3n, r2, s3a, abfss

lakeFS is currently working with https scheme for Azure, and therefore when providing the table path we fail to register the table.

Note that according to the above error message external locations are supported only in ADLS gen2 (no wasb scheme support)

One solution is to convert the https scheme into an abfss one in the unity exporter before registering the table.
