Unified Analytics

This topic describes the Unified Analytics known issues for Cloudera Data Warehouse Private Cloud.

Known issues identified in 1.5.0

DWX-13362: Queries containing simple SELECT statements get cached
A query such as SELECT * FROM planes LIMIT 2; gets cached. This is an undesirable result and will be fixed in a future release.
DWX-8348: Service Discovery does not work when Impala is enabled with Unified Analytics
Impala provides multiple endpoints for clients, such as Impala coordinator, impala-proxy, and Hive Server2 (HS2) (when Impala Virtual Warehouse is used in Unified Analytics mode). When Impala is enabled with Unified Analytics, both coordinator and HS2 endpoints are active, which interferes with Service Discovery.

To resolve this issue perform the following steps:
  1. Log in to the Data Warehouse service as DWAdmin.
