Q: 

How to write and read files in/from Hadoop HDFS using Ruby?

Is there a way to work with HDFS Api using Ruby? As I can understand there is no multilanguage file Api and the only way is to use native Java Api. I tried using JRuby but this solution is to unstable and not very native. Also I looked at HDFS Thrift Api but it's not complete and also lacks many features (like writing to indexed files).

Is there a way to work with HDFS using Ruby besides from using JRuby or Thrift Api?
