I work for a databricks partner called Cirata.  Our Data migrator offering allows  both data and metadata replication  from cloudera to be delivered to the databricks environment , whether this is just delivering it to the ADLS2 object storage or to Databricks in Delta lake format and the Unity catalog.  We do this without any business interruption at the source and can keep both source and target insync as updates are applied to the source.  see http:\\www.cirata.com  or contact me at adrian.ashley@cirata.com  for further information
