How to Install Hive for Mac: A Step-by-Step Guide

As a developer or data analyst, you may have come across Hadoop and Hive, two popular open-source tools used for big data processing and analysis. However, installing Hive on your Mac can be a bit tricky, especially when it comes to setting up the metastore with MySQL instead of Derby. In this article, we'll provide a step-by-step guide on how to install Hive for Mac and set up a MySQL metastore.

Before you start, make sure you have Hadoop installed on your Mac. If not, refer to our previous post on installing Hadoop for help. Once you have Hadoop up and running, let's move on to installing Hive using Homebrew.

Installing Hive with Homebrew

Homebrew is a popular package manager for macOS that makes it easy to install and manage software packages. To install Hive using Homebrew, follow these steps:

1. Open your terminal and run the following command: `brew install hive`

2. This will take some time as Homebrew installs Hive and its dependencies.

3. Once the installation is complete, add Hive to your PATH by editing your bash profile.

Editing Your Bash Profile

To edit your bash profile, follow these steps:

1. Open your terminal and run the following command: `nano ~/.bash_profile`

2. Add the following lines at the end of the file: `export HIVE_HOME=/usr/local/hive` `export PATH=$PATH:$HIVE_HOME/bin`

3. Press Ctrl+X to exit nano, then press Y to save the changes.

Setting Up a MySQL Metastore

By default, Hive uses Derby as its metastore, but we'll set up a MySQL metastore instead. To do this, follow these steps:

1. Install MySQL on your Mac if you haven't already.

2. Create a new database in MySQL and grant privileges to the Hive user.

3. Edit your Hive configuration file (`hive-site.xml`) to point to your MySQL database.

That's it! With these steps, you should now have Hive installed and set up with a MySQL metastore on your Mac. If you encounter any issues during the installation process, refer to our previous post on installing Hadoop for help.

In conclusion, installing Hive on Mac can be a bit tricky, but with Homebrew and a few tweaks to your bash profile, you should be able to get it up and running in no time.
