Upgrade your search head for Hunk

Download and install the new version of Hunk

You first need to upgrade your search head by installing the newest version of Hunk. To install Hunk on your system, you download the Linux distribution for Splunk 6.x and install it, then add a Hunk license.

You can find the correct version to download here: http://www.splunk.com/download/hunk

You must configure this installation to run on a search head that resides on a *nix platform. You can run Hunk on any machine that meets the requirements for a search head. For more information about search heads, see Configure the search head.

Note: Hunk is not supported on Windows.

If you want to learn more about installing or updating Splunk, see "Install on Linux" in the Installation manual.

Tar file install

To install on a Linux system, expand the tarball into an appropriate directory using the tar command:

tar xvzf splunk_package_name.tgz

The default install directory is splunk in the current working directory. To install into /opt/splunk, use the following command:

tar xvzf splunk_package_name.tgz -C /opt

Note: When you install with a tarball:

• Some non-GNU versions of tar might not have the -C argument available. In this case, if you want to install in /opt/splunk, either cd to /opt or place the tarball in /opt before running the tar command. This method will work for any accessible directory on your machine's filesystem.
• Splunk does not create the splunk user automatically. If you want Hunk to run as a specific user, you must create the user manually before installing.
• Ensure that the disk partition has enough space to hold the uncompressed volume of the data you plan to keep indexed.

Edit indexes.conf

In your indexes.conf file, change the attribute vix.splunk.setup.package so that it provides the path to the new Splunk .tgz package that Splunk can install and use on data nodes. The next time MapReduce spawns a search, Splunk pushes the new package to the nodes and upgrades the version stored on on the Data Node and Task Tracker.

See "Set up a provider and virtual index in the configuration file" for more information about editing configuration files.

See "Provider configuration variables" for more information about editing this attribute in the Hunk user interface.
