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

• Alpha Status (Rust wrapping APIs can be changed)
• All libhdfs FFI APIs are ported.
• Safe Rust wrapping APIs to cover some of the libhdfs APIs.

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

• Hadoop compiled with native library (i.e., maven profile-Pnative)
  • Please refer tohttps://github.com/apache/hadoop/blob/trunk/BUILDING.txt if you need more description.

Add this to your Cargo.toml:

[dependencies]hdfs ="0.0.4"

and this to your crate root:

externcrate hdfs;

hdfs-rs uses libhdfs, which is JNI native implementation. JNI native implementation requires the properCLASSPATH.exec.sh included in the source code root plays a role to execute your program with the properCLASSPATH.exec.sh requiresHADOOP_HOME. So, you firstly setHADOOP_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```
