Dashboard

Apache Solr dynamic Dashboards:

 

Supportability

  • Bug fixes
    • UX improvements (document listing, opening back query history scroll, CTRL+Z…)
    • Performances (concurrency, file downloads, query timeouts)
    • Support multi-authentication with LDAP
    • YARN “Diagnostics” info in Job Browser
    • Option to disable concurrent user sessions “concurrent_user_session_limit”
    • Rebalance user on log out
    • Editor grid result not correctly aligned when browser zoom is not 100%

 

Demo use case: Customer 360

In this Self Service analytics Customer 360 demo we use the Editor to query credit card transaction data that is saved in an object store in the cloud (here S3) and in a Kudu table. The demos leverages the Data Catalog search and tagging as well as the Query Assistant.

Onwards!

    When i click sample tab on table browser, error of hdfs permission denied for user hue is occurred.
    My personal id has hdfs permission, but user hue does not have hdfs permission.
    How to change get sample operation to use personal user?

    • LJ 6 months ago

      In previous version Hue 4.1, “Get Sample Operation” was used personal user.
      I try to find difference of configuration in hue.ini with Hue 4.1 and Hue 4.2, but i can’t find it.

        Hum, this sounds like a bug, the query of data sample should still run as the logged-in user. We are investigating.

    Hi Team,
    When i click on Editor — > Scala, am getting error – > The spark session could not be created in the cluster : timeout, can you please help on this.

      You need a REST Spark server running (like Apache Livy) to have that working
