HappyBase is a developer-friendly Python library to interact with Apache HBase. HappyBase is designed for use in standard HBase setups, and offers application developers a Pythonic API to interact with HBase. Below the surface, HappyBase uses the Python Thrift library to connect to HBase using its Thrift gateway, which is included in the standard HBase 0.9x releases.
