Figure 1. New Metadata Source Wizard

How to verify the extracted Metadata File

Access the Cloudera Octopai Target Folder (TGT)

  1. Go to the TGT Folder located on the Server where the Cloudera Octopai Client is installed. By default: C:\Program Files (x86)\Octopai\Service\TGT
  2. Open the zip file having the Connector Name. Example:
  3. Verify its content: Quantity & Quality of inner files

Troubleshoot
