What you need on your Hadoop nodes

On Hadoop TaskTracker nodes you need a directory on the *nix file system running your Hadoop nodes that meets the following requirements:

  • One gigabyte of free disk space for a copy of Splunk.
  • 5-10GB of free disk space for temporary storage. This storage is used by the search processes.

What you need on your Hadoop file system

On your Hadoop file system (HDFS or otherwise) you will need:

  • A subdirectory under jobtracker.staging.root.dir (usually /user/) with the name of the user account under which Splunk Analytics for Hadoop is running on the search head. For example, if Splunk Analytics for Hadoop is started by user "BigDataUser" and jobtracker.staging.root.dir=/user/ you need a directory /user/HadoopAnalytics that is accessible by user "BigDataUser".
  • A subdirectory under the above directory that can be used by this server for intermediate storage, such as /user/hadoopanalytics/server01/
