To identify the Tez DAG for your job:

  1. Navigate to the Tez View instance by clicking Go to instance on the Tez View page in Ambari. The Tez View instance page displays a list of jobs sorted by time, listing the latest jobs first. You can search a job using the following fields:

    • Dag Name (DAG name for the job)

    • Id (DAG identifier)

    • Submitter (user who submitted the job)

    • Status (job status)

    • Application ID

  2. When you have entered your search criteria, press Enter, and search results matching your criteria are returned below.

Selecting the Columns That Appear in Search Results

To select which columns are included in the Tez View search results, click the gear icon to the right of the search tool bar. A Column Selector dialog box appears where you can select which columns appear in the search results. Select the columns, and click Ok to return to the Tez View:
