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 in Hue to create tables from files, Hue creates a Hive
table by default (if Hive is available) and uses the first available Hive Virtual
Warehouse. You cannot select a specific Virtual Warehouse during file import. To
create an Impala table using the Importer, you must first select the editor type as
Impala, and then click + on the Table
Browser.
