Installing the Hadoop plug-in

Log on to the Veritas Support site to download the Hadoop plug-in and store it in a local directory.

Use your Entitlement ID to locate the PSF plug-ins and download the NetBackup_PSF_Hadoop_Plugin_8.1-BuildID.tar.gz file.

See Downloading the Hadoop plug-in.

You must install Hadoop plug-in on all the media servers, clients, or master server you want to use as backup host.

To install Hadoop plug-in on a backup host

  1. Login to the backup host with root privileges.
  2. Extract the plug-in. Run the following command:

    tar -xvf package_name

    Following files are extracted:

    • plug-in_pkg.linuxR_x86.tar

    • plug-in_pkg.linuxS_x86.tar

    • install

    • LICENSE

  3. Run the installer. Run the following command:

    ./install

  4. Accept the End User License Agreement (EULA).

    Enter y for the prompt.

  5. Following plugin-in binaries are installed in /usr/openv/lib/ directory:

    • libaapihdfs.so

    • libaapipgnhadoop.so
