smart_open - Utils for streaming large files (S3, HDFS, gzip, bz2...)
There are a few optional keyword arguments that are useful only for S3 access. These are both passed to boto.s3_connect() as keyword arguments. The S3 reader supports gzipped content, as long as the key is obviously a gzipped file (e.g. ends with ".gz").

Ibis is a toolbox to bridge the gap between local Python environments, remote storage, execution systems like Hadoop components (HDFS, Impala, Hive, Spark) and SQL databases. Its goal is to simplify analytical workflows and make you more productive. Learn more about using the library at http://ibis-project.org.

Apache Spark is an open source cluster computing system that aims to make data analytics fast — both fast to run and fast to write. To run programs faster, Spark offers a general execution model that can optimize arbitrary operator graphs, and supports in-memory computing, which lets it query data faster than disk-based engines like Hadoop.
cluster cluster-computing data-analytics analytics hdfs map-reduce big-datasnakebite - A pure python HDFS client
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.
hdfs python-hdfs-clienthdfs - A native go client for HDFS
This is a native golang client for hdfs. It connects directly to the namenode using the protocol buffers API. It tries to be idiomatic by aping the stdlib os package, where possible, and implements the interfaces from it, including os.FileInfo and os.PathError.

Dynamometer is a tool to performance test Hadoop's HDFS NameNode. The intent is to provide a real-world environment by initializing the NameNode against a production file system image and replaying a production workload collected via e.g. the NameNode's audit logs. This allows for replaying a workload which is not only similar in characteristic to that experienced in production, but actually identical. Dynamometer will launch a YARN application which starts a single NameNode and a configurable number of DataNodes, simulating an entire HDFS cluster as a single application. There is an additional workload job run as a MapReduce job which accepts audit logs as input and uses the information contained within to submit matching requests to the NameNode, inducing load on the service.

I am currently following and testing against the WebHDFS REST API documentation for the 1.2.1 release, by Apache. Make sure you enable WebHDFS in the hdfs site configuration file. I use Mocha and should.js for unit testing. They will be required if you want to run the unit tests. To execute the tests, simply npm test, but install the requirements first. You will also likely need to adjust the constants in the test file first (or have a username "ryan" setup for hosts "endpoint1" and "endpoint2").
hdfs webhdfs httpros_hadoop - Hadoop splittable InputFormat for ROS
RosbagInputFormat is an open source splittable Hadoop InputFormat for the ROS bag file format. For an example of rosbag file larger than 2 GB see doc/Rosbag larger than 2 GB.ipynb Solved the issue https://github.com/valtech/ros_hadoop/issues/6 The issue was due to ByteBuffer being limitted by JVM Integer size and has nothing to do with Spark or how the RosbagMapInputFormat works within Spark. It was only problematic to extract the conf index with the jar.

Because the world needs yet another way to talk to HDFS from Python. This library provides a Python client for WebHDFS. NameNode HA is supported by passing in both NameNodes. Responses are returned as nice Python classes, and any failed operation will raise some subclass of HdfsException matching the Java exception.
