Install Pinot via Mpack

Perform the following steps to install Pinot via Mpack.

Download the Pinot mpack from the Mpacks Link.

JDK Installation

For RHEL/CentOS systems:

sudo dnf install java-17-openjdk-devel -y

python -m pip install requests

Register Custom Java 17 with `update-alternatives` (for Script Compatibility)

If you have installed JDK 17 via a custom method (e.g., extracting from a .tar.gz or placing it under a non-standard path), the following script may fail to detect your Java 17 installation:

This is because the script relies on the output of update-alternatives to find valid Java 17 paths that follow a naming pattern like /usr/lib/jvm/java-17-*. If your custom Java is not registered under this directory, the script will not detect it, even if it is installed and working.

Solution: Register Java 17 (without setting it as default)

You can register your custom Java 17 installation with update-alternatives without making it the system default. This allows the script to locate the JDK while keeping your current system-wide Java version unchanged.

Info

To ensure compatibility with the script, place or link your custom JDK under /usr/lib/jvm/ using a name that starts with java-17.

Move or link your custom JDK under /usr/lib/jvm.

sudo mv /path/to/custom/java-17 /usr/lib/jvm/java-17-custom

Alternatively, create a symlink:

sudo ln -s /path/to/custom/java-17 /usr/lib/jvm/java-17-custom

# Ubuntu/Debian: sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-17-custom/bin/java 1 # RHEL/CentOS: sudo alternatives --install /usr/bin/java java /usr/lib/jvm/java-17-custom/bin/java 1

(Optional) Verify the registration:

update-alternatives --display java

You must now see the /usr/lib/jvm/java-17-custom/bin/java listed as one of the configured alternatives.

Info

Do not run update-alternatives --config java unless you explicitly want to change the system default Java version.

For Ubuntu/Debian systems:

sudo apt install openjdk-17-jdk -y

python -m pip install requests

Install the Mpack using Ambari:

ambari-server install-mpack --mpack={Pinot_Mpack_Name} --verbose

Restart Ambari server:

ambari-server restart

Install Pinot Service via Ambari

Use the Ambari UI to install the Pinot service. The process is automated—simply select the target hosts for Pinot components and proceed with the installation.

Info

Configure the JVM options in the Pinot Broker Java Virtual Machine (JVM) options.

Info

If you're using a custom JDK 17 path and are unable to register it using the update-alternatives command, add the Java 17 path to the JAVA_HOME setting under Advanced pinot-env configuration. For more information, Install JDK 17 .

Info

Basic authentication is enabled by default. You can disable it by unchecking the "Basic Auth" option during the setup.
