Base Storage Layer

When the is first installed, the base storage layer must be set.

NOTE: After you have begun using the product, you cannot change the base storage layer.


For more information, see Set Base Storage Layer.

Storage - WASB

For read/write access to WASB, the base storage layer must be set to WASB. For more information, see Enable WASB Access.

Storage - ADLSFor read/write access to ADLS, the base storage layer must be set to HDFS. For more information, see Enable ADLS Access.
Storage - SQL DBFor Azure installs, you can optionally create a connection to an Azure-hosted instance of SQL DB. For more information, see Create SQL DB Connections.
Storage - SQL DWFor Azure installs, you can optionally create a connection to an Azure-hosted instance of SQL DW. For more information, see Create SQL DW Connections.

  • The can integrate with at most one cluster. It cannot integrate with two different clusters at the same time.
  • Smaller jobs can be executed on the running environment, which is hosted on the itself.
  • For more information, see Running Environment Options.

Azure Installations

All Azure installations are executed through the Azure Marketplace. Then, the platform can be integrated with a pre-existing HDI cluster or a cluster that you create as part of the installation. 

For more information, see Install from Azure Marketplace.
