Cloudera Data Warehouse allows you to deploy a
shared Hue service at an environment level. Learn about the advantages and limitations of
deploying a shared Hue service and some FAQs that can help you understand more about the
feature.
Advantages of deploying a shared Hue service🔗
By deploying a shared Hue service, you can manage costs by keeping only
those Virtual Warehouses running that your users need at that time. Data analysts
only need to know or bookmark one Hue instance URL and can run queries on any
Virtual Warehouses available to them.
Each shared Hue service instance has its own database where queries and
query history are saved. Moreover, the shared Hue service remains active as long as
the environment is active.
Limitations🔗
When you use the Importer to create tables from files in Hue, by default, Hue creates
a Hive table if Hive is available and uses the first Hive Virtual Warehouse that was
created. You cannot select a Virtual Warehouse using which you want to create a
table by importing a file. To create an Impala table using the Importer, you must
first select the editor type as Impala and then click + on
the Table Browser.
