Installing Apache Hive LLAP
Hive low-latency analytical processing (LLAP) provides you with extended query execution in Hive that consists of:
A persistent daemon that provides execution and caching of data
A tightly integrated directed acyclic graph (DAG)-based framework
The primary benefit of using LLAP is to enhance your query execution times. Small, short queries can be processed by the daemon. For more information about LLAP, refer to Hive LLAP on Your Cluster.
