What Can I Do If Device Performance Data Is Not Displayed on the Controller?

Question

Device performance data is not displayed on the controller, and a log that contains "Token has expired" can be found in Yarn tasks on FusionInsight Manager.

Answer

1. Log in to FusionInsight Manager as the admin user.
2. Choose Cluster > Spark2x > Configurations > All Configurations from the main menu.
3. Choose SparkResource2x > Customization, and set Name and Value next to custom to spark.security.credentials.renewalRatio and 0.000000000007, respectively.

   If the following window is displayed, close it.

4. Choose JDBCServer2x > Customization, and set Name and Value next to custom to spark.security.credentials.renewalRatio and 0.000000000007, respectively.

   If the following window is displayed, close it.

5. Click Save in the upper left corner of the page.

6. On the Save Configuration page that is displayed, click OK. The configuration is saved successfully after about 1 minute.

7. Choose Cluster > Spark2x > Dashboard and choose More > Restart Service in the upper right corner of the page.

8. On the Verify Identity page, enter the login password for the admin user and click OK.

9. Modify the FusionInsight client configuration on the controller server.
   1. Log in to the controller server as the sopuser user and switch to the ossuser user.
   2. Modify the FusionInsight client configuration. Run the following command to go to the /opt/hadoopclient/Spark2x/spark/conf/ directory:

      cd /opt/hadoopclient/Spark2x/spark/conf/

      If the directory does not exist on the server, you do not need to perform the following operations. If the directory exists, run the following command:

      vi spark-defaults.conf

      Change the spark.security.credentials.renewalRatio value in the vi spark-defaults.conf file as follows. If the parameter does not exist, add it to the end of this file.

      spark.security.credentials.renewalRatio = 0.000000000007
