Hive (SQL)

📘

Prerequisites

To complete this guide, you will need permissions to create users on Hive (if authentication is enabled).

To connect Monte Carlo to a Hive to run data health SQL queries, follow these steps:

  1. Create a Hive cluster for Monte Carlo's data health queries using AWS EMR. Alternatively, you may use an existing cluster that you already have in your environment.
  2. Ensure that Monte Carlo's data collector has network connectivity to the cluster.
  3. Create a service account on Hive if necessary.
  4. Provide service account credentials to Monte Carlo.

Providing account credentials to Monte Carlo

You will provide connection details for Hive (SQL) using Monte Carlo's CLI:

  1. Please follow this guide to install and configure the CLI.
  2. Please use the command montecarlo integrations add-hive to set up Hive connectivity. For reference, see help for this command below:
$ montecarlo integrations add-hive --host ec2-18-188-136-250.us-east-2.compute.amazonaws.com --port 10000 --database default --auth-mode NOSASL --help
Usage: montecarlo integrations add-hive [OPTIONS]

  Setup a Hive SQL integration. For health queries.
