Hi Thanks for checking. Our Druid installation has Sql Server as metastore, and it is using Azure for Deep storage. It is working fine. That is why i was wondering why Hive would need MySQL or Postgres only for Druid integration.
I'm using Hive 2.2.0 Now dismantling Druid just for Hive integration is a big effort to do i would guess.
