    Description

      Hitchhiker is a new erasure coding algorithm developed as a research project at UC Berkeley. It has been shown to reduce network traffic and disk I/O by 25%-45% during data reconstruction while retaining the same storage capacity and failure tolerance capability as RS codes. This JIRA aims to introduce Hitchhiker to the HDFS-EC framework, as one of the pluggable codec algorithms.

      The existing implementation is based on HDFS-RAID.
