Indexing data with Apache Pig

Apache Pig (https://pig.apache.org/) is a tool that's frequently used to store and manipulate data in data stores. It can be very handy if you need to import some Comma-Separated Values (CSV) in Elasticsearch very quickly.

Getting ready

You need a working Pig installation. Depending on your operating system, you should follow the instructions at http://pig.apache.org/docs/r0.17.0/start.html.

tar xfvz pig-0.17.0.tar.gz
