Setting up Hunk

In order to start exploring Hadoop data, we have to install Hunk on top of our Hadoop Cluster. Hunk is easy to install and configure. Let's learn how to deploy Hunk version 6.2.1 on top of an existing CDH cluster. It's assumed that your VM is up and running.

Extracting Hunk to a VM

1. Open the console application.

2. Run ls -la to see the list of files in your home directory:

   [cloudera@quickstart ~]$ cd ~
   [cloudera@quickstart ~]$ ls -la | grep hunk
   -rw-r--r--   1 root     root     113913609 Mar 23 04:09 hunk-6.2.1-249325-Linux-x86_64.tgz
   

3. Unpack the archive:

   cd /opt
   sudo tar xvzf /home/cloudera/hunk-6.2.1-249325-Linux-x86_64.tgz -C /opt
   

Setting up Hunk variables and configuration files

1. It's time to set the SPLUNK_HOME environment variable. This variable has already been added to the profile:

   export SPLUNK_HOME=/opt/hunk
   

2. Use the default splunk-launch.conf. This is the basic properties file used by the Hunk service. We don't have to change anything special, so let's use the default settings...
