This page describes how Pig interoperates with other platforms, such as HBase and Hive.
Pig and Cassandra
Starting with Pig 0.7, there is a LoadStoreFunc for Cassandra. Download the Cassandra src and it's currently in a contrib module (http://cassandra.apache.org/download/
). Details are found in the readme there. More hadoop support details are found here: http://wiki.apache.org/cassandra/HadoopSupport. A project that looks to ease integration between the two is Pygmalion: https://github.com/jeromatron/pygmalion/.
Pig and HBase
In Pig 0.6 and before, the built in HBaseStorage can be used to load data from Hbase. Work is ongoing to enhance this loader and make it a storage function also. See http://issues.apache.org/jira/browse/PIG-1205
Pig and Hive RCFiles
The HiveColumnarLoader, available as part of PiggyBank in Pig 0.7.0.
Pig and Voldemort
The Pig LoadFunc for Voldemort.
See http://github.com/rsumbaly/voldemort/blob/hadoop/contrib/hadoop/src/java/voldemort/hadoop/pig/VoldemortStore.java
Pig and Avro
AvroStorage, an Avro LoadFunc/StoreFunc in piggybank. See https://issues.apache.org/jira/browse/PIG-1748
