In Advanced Options set up Spark config for a connection to ADLS storage. Configuration is a set of key:value pairs separated by single spaces.

Spark metastore version spark.sql.hive.metastore.version 1.2.1
Spark drivers spark.sql.hive.metastore.jars builtin
OAuth access type spark.hadoop.dfs.adls.oauth2.access.token.provider.type ClientCredential
OAuth login endpoint spark.hadoop.dfs.adls.oauth2.refresh.url https://login.microsoftonline.com/6fdc3117-ec29-4d73-8b33-028c8c300872/oauth2/token
OAuth secret spark.hadoop.dfs.adls.oauth2.credential +gv2ThjPc++++++++++++++++++++++++++zV8NrM74=
OAuth client ID spark.hadoop.dfs.adls.oauth2.client.id 74731c8c-7290-4998-8005-1d0670cbe909
