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.

Unsupported features

Importing and exporting Oozie workflows across clusters and between different CDH versions is not supported: You can export Oozie workflows, schedules, and bundles from Hue and import them only within the same cluster. It is not recommended to use the import-export feature to migrate data between clusters. To migrate data between different versions of CDH, for example from CDH 5 to CDP 7, you must migrate the database and add it to the newly created cluster.
