Sending Diagnostic Data to Cloudera for YARN Applications

You can send diagnostic data collected from YARN applications, including metadata, configurations, and log data, to Cloudera Support for analysis. Include a support ticket number if one exists to enable Cloudera Support to address the issue more quickly and efficiently.

  1. From the YARN page in Cloudera Manager, click the Applications menu.
  2. Collect diagnostics data. There are two ways to do this:
    • To collect data from all applications that are visible in the list, click the top Collect Diagnostics Data button on the upper right, above the list of YARN applications.
    • To collect data from only one specific application, click the down arrow on the right-hand end of the row of the application and select Collect Diagnostics Data.


  3. In the Send YARN Applications Diagnostic Data dialog box, provide the following information:
    • If applicable, the Cloudera Support ticket number of the issue being experienced on the cluster.
    • Optionally, add a comment to help the support team understand the issue.
  4. Click the checkbox Send Diagnostic Data to Cloudera.
  5. Click the button Collect and Send Diagnostic Data.
