-------------------------------
Summary: Implement the Hitchhiker erasure coding algorithm
Key: HDFS-7715
URL: https://issues.apache.org/jira/browse/HDFS-7715
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Zhe Zhang
[Hitchhiker |
http://www.eecs.berkeley.edu/~nihar/publications/Hitchhiker_SIGCOMM14.pdf] 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% and 45% during
data reconstruction. 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.
