Comment:
Per stack, changing the repo to Todd's version of LZO

  
  This distro doesn't contain all bug fixes (such as when LZO header or block header data falls on read boundary).
  
- Please get latest distro with all fixes from http://github.com/kevinweil/hadoop-lzo

  == Why compression? ==
  By enabling compression, the store file (HFile) will use a compression algorithm on blocks as they are written (during flushes and compactions) and thus must be decompressed when reading.
