This is a fork of https://github.com/spotify/snakebite, via https://github.com/kirklg/snakebite/tree/feature/python3. We maintain it enough to work for our needs at the Internet Archive. We use the library with our CDH5 cluster and have not tested it with any other versions of hadoop. Please help us improve this! Or make your own fork. No hard feelings.

Snakebite is a python library that provides a pure python HDFS client and a wrapper around Hadoops minicluster. The client uses protobuf for communicating with the NameNode and comes in the form of a library and a command line interface. Currently, the snakebite client supports most actions that involve the Namenode and reading data from DataNodes.

Note: all methods that read data from a data node are able to check the CRC during transfer, but this is disabled by default because of performance reasons. This is the opposite behaviour from the stock Hadoop client.

Snakebite requires python2 (python3 is not supported yet) and python-protobuf 2.4.1 or higher.

Snakebite 1.3.x has been tested mainly against Cloudera CDH4.1.3 (hadoop 2.0.0) in production. Tests pass on HortonWorks HDP 2.0.3.22-alpha (protocol versions 7 and 8)

Snakebite 2.x has been tested on Hortonworks HDP2.0 and CDH5 Beta and ONLY supports Hadoop 2.2.0 and up (protocol version 9)!

Snakebite-py3 releases will be available through pypi at https://pypi.python.org/pypi/snakebite-py3/

To install snakebite run:

pip install snakebite-py3
