About Hue Query Processor
The Hue Query Processor indexes and retrieves Hive query history and query details 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.
The Query Processor inherits Kerberos and Auto-TLS configurations from your Cloudera Manager-based cluster.
The Hue Query Processor indexes and retrieves Hive query history by reading query event data from a Hadoop Compatible File System (HCFS), such as S3, and writing them into a relational database, such as PostgreSQL. The Query Processor pod runs at the Database Catalog level.
