Known issues

  • Reports tab is not present in the full-featured DAS version.


    1. Set up the SmartSense ID in DAS configurations.
      1. On the Ambari UI, go to Data Analytics Studio > Configs.
      2. Under Advanced data_analytics_studio-webapp-properties, specify das-smartsense-id in the Dataplane Smartsense id field.
    2. Restart the DAS service.
  • DAS displays the queue name on the Query Details page only when the query is run against llap. If you run a query against any other queue, DAS does not display the queue name.
  • You might face UI issues on Google Chrome while using faceted search, for example. We recommend you to use the latest version of Google Chrome (version 71.x or higher).
  • You are unable to see databases or the query editor on the Compose page even after following the troubleshooting procedure. This can be caused due to incorrect hive service name in ZooKeeper.
  • DAS fails to connect to Hive on an HDP 2.6.x cluster, if the transport mode is binary. The Hive interactive server transport mode should be http if you are using HDP 2.6.x
  • Visual Explain for the same query shows different graphs on the Compose page and the Query Details page.
  • While running some queries, if you restart HSI, the query execution is stopped. However, DAS does not reflect this change and the queries appear to be in the same state forever.
  • After a fresh installation, when there is no data and you try to access the Reports tab, it throws HTTP 404 Not Found Error.
  • When you try to load a database with more than 3000 tables, the Compose page crashes.
  • Join count does not get updated for tables with partitioned columns.
