Installing Ranger Plug-ins

The following sections describe how to install Ranger plug-ins.

Note

To ensure that you are installing the HDP version of the plug-ins instead of the Apache version, make sure you enter the following commands when installing each plug-in:

For CentOS and RHEL:
```
yum install ranger_ <version_number>
```

For SLES:

zypper -n --no-gpg-checks install --auto-agree-with-licenses ranger_ <version_number>

For Debian/Ubuntu:
HDP support for Debian 6 is deprecated with HDP 2.4.2. Future versions of HDP will no longer be supported on Debian 6.
```
apt-get install <version_number>
```

Installing the Ranger HDFS Plug-in

The Ranger HDFS plug-in helps to centralize HDFS authorization policies.

This section describes how to create an HDFS repository and install the HDFS plug-in.

Install the HDFS Plug-in

Create a Ranger HDFS policy using the instructions in Create an HDFS Policy in the Hadoop Security Guide.
Make a note of the name you gave to this repository; you will need to use it again during HDFS plug-in setup.

At all servers where NameNode is installed, install the HDFS plug-in by following the steps listed below:

Go to the home directory of the HDFS plug-in:
```
cd /usr/hdp/<version>/ranger-hdfs-plugin
```

Edit the following HDFS-related properties in the install.properties file:
