Known Issues in Hue

Learn about the known issues in Hue, the impact or changes to the functionality, and the workaround.

Impala editor fails silently after SAML SSO session times out

When you run a query from an Impala editor in Hue, the Impala editor may silently fail without displaying an error message. As a result, you may not see any action on the screen after submitting your query. This happens if Hue is configured with SAML authentication and you run a query from a browser session that has remained open for a period longer than the SSO maximum session time set by the SAML Identity Provider.

Workaround: If you do not see any action on the Impala editor after submitting the query, refresh the page on your browser.

BalancerMember worker hostname too long error
You may see the following error message while starting the Hue Load Balancer:
BalancerMember worker hostname (xxx-xxxxxxxx-xxxxxxxxxxx-xxxxxxx.xxxxxx-xxxxxx-xxxxxx.example.site) too long.

Cloudera Manager displays this error when you create a Data Hub cluster using the Data Engineering template and the Hue Load Balancer worker node name has exceeded 64 characters. In a CDP Public Cloud deployment, the system automatically generates the Load Balancer worker node name through AWS or Azure.

For example, if you specify cdp-123456-scalecluster as the cluster name, CDP creates cdp-123456-scalecluster-master2.repro-aw.a123-4a5b.example.site as the worker node name.

Specify a shorter cluster name while creating a Data Hub cluster so that the final worker node name does not cross 64 characters.

For example, cdp-123456-scale.
