Zhe Zhang created HDFS-7715: ------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
