About Hue Query Processor
The Hue Query Processor service indexes Hive and Impala query history and provides APIs to access them. Enabling the processor allows you to view Hive query history and query details on the Queries tab on the Hue Job Browser page.
You can enable or disable Hue to display the Queries tab by selecting or deselecting the Query Processor Service option in the Hue Advanced Configuration Snippet in Cloudera Manager.
