Hive on Tez: How Do I Resolve the Timeout Warning Message for Dashboards?

TROUBLESHOOTING

Issue description: A timeout warning message is displayed when you try to open a dashboard based on a Hive on Tez data source. This is possibly being caused by the configuration of the Hive on Tez server.
Workaround: If you are encountering timeout errors, you can first try to create or modify the settings in Zoomdata's configuration file - zoomdata.properties :

Access the article Managing Configurations in Zoomdata for information about this file.
  • Increase the timeout value that causes this exception to 2 minutes:
    hive.tez.ds.max.wait.time.sec=120
  • If the Hive on Tez server has at least 64 GB storage and 16 cores, modify the values for the following parameters:
    hive.tez.ds.max.idle=5
    hive.tez.ds.max.active=5
