Metadata Access Service

Metadata Access Service

You can configure the Metadata Access Service. Metadata Access Service is an application service that allows the Developer tool to access Hadoop connection information to import and preview metadata from multiple Hadoop distributions.
  1. If you selected to create a Metadata Access Service during the installation, the
    Metadata Access Service
    page appears.
  2. Configure the service properties for the Metadata Access Service.
    The following table lists the service properties for the Metadata Access Service:
    Property
    Description
