Running the Pig demo

Examples demonstrate how to use Pig to work with CQL tables.

Three examples demonstrate how to use Pig to work with CQL tables.

How to save Pig relations from/to Cassandra

Pig uses a single tuple.
How to work with a Cassandra compound primary key in Pig

Pig uses three tuples, one for the partition key and two for the two clustering columns.
How to use Pig to set up logic for exploring library data

This example from the Cassandra and Pig tutorial shows how to copy public library data into Cassandra, add logic to save the data to a Pig relation, execute programs by running MapReduce jobs, and view results in a Cassandra table.

Start Pig

Note:

DataStax Demos do not work with LDAP or internal authorization (username/password) enabled.

Start DataStax Enterprise as an analytics (Hadoop) node:
- Installer-Services and Package installations:
  1. Set HADOOP_ENABLED=1 in /etc/default/dse.
  2. Start an analytics node:
```
$ sudo service dse start
```
- Installer-No Services and Tarball installations:
```
$ DSE_install_location/bin/dse cassandra -t
```
Start the Pig shell:
- Installer-Services and Package installations: $ dse pig
- Installer-No Services and Tarball installations: $ DSE_install_location/bin/dse pig
The Pig grunt prompt appears, and you can now enter Pig commands.
