HDFS binding and wrapper APIs for Rust

hdfs-rs

libhdfs binding library and rust APIs which safely wraps libhdfs binding APIs

Documentation

• [API documentation] (http://hyunsik.github.io/hdfs-rs/)

Requirements

• Hadoop which is compiled with -Pnative
  • Please refer to https://github.com/apache/hadoop/blob/trunk/BUILDING.txt if you need more description.

Usage

Add this to your Cargo.toml:

[dependencies]
hdfs = "0.0.2"

and this to your crate root:

extern crate hdfs;

hdfs-rs uses libhdfs, which is JNI native implementation. JNI native implementation requires the proper CLASSPATH. exec.sh included in the source code root plays a role to execute your program with the proper CLASSPATH. exec.sh requires HADOOP_HOME. So, you firstly set HADOOP_HOME shell environment variable as follows:

export HADOOP_HOME=<hadoop install dir>
```

Then, you can execute your program as follows:

```bash
./exec your_program arg1 arg2
```
