I want to write an Hadoop decompression codec for LZMA2 that can read .xz files.
This is my assignment and I am totally new to Compression or Decompression codec.
I am seeking some guidance on this issue.From where I should start and where I will get corresponding help for this task?
You will need to implement the CompressionCodec interface as well as Compressor and Decompressor for LZMA2. You can look at the GzipCodec code in Hadoop for an example of how to do this.
