Install Pinot via Mpack

Perform the following steps to install Pinot via Mpack.

Install JDK 11

For RHEL/CentOS systems:

sudo dnf install java-11-openjdk-devel -y

python -m pip install requests

Register Custom Java 11 with update-alternatives (for Script Compatibility)

If you have installed JDK 11 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 11 installation:

This is because the script relies on the output of update-alternatives to find valid Java 11 paths that follow a naming pattern like /usr/lib/jvm/java-11-*. 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 11 (without setting it as default)

You can register your custom Java 11 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.

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

sudo mv /path/to/custom/java-11 /usr/lib/jvm/java-11-custom

Alternatively, create a symlink:

sudo ln -s /path/to/custom/java-11 /usr/lib/jvm/java-11-custom

2. Register the JDK with update-alternatives.

# Ubuntu/Debian:

sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-11-custom/bin/java 1

​

# RHEL/CentOS:

sudo alternatives --install /usr/bin/java java /usr/lib/jvm/java-11-custom/bin/java 1

3. (Optional) Verify the registration:

update-alternatives --display java

You must now see the /usr/lib/jvm/java-11-custom/bin/java listed as one of the configured alternatives.

For Ubuntu/Debian systems:

sudo apt install openjdk-11-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
