Setting up LLAP

Using Ambari, you can set up basic, low-latency analytical processing (LLAP) by accepting the default llap queue, changing some YARN queue properties, and adding a HiveServer property to hive-site.xml.

  • You have installed Ambari 2.7.x or later.
  • You added and started YARN, Tez, and dependencies that Ambari prompts you to add.
  • You added, started, and can run conventional queries from the Hive service.
