> Key: HADOOP-15558
> URL: https://issues.apache.org/jira/browse/HADOOP-15558
> Project: Hadoop Common
> Issue Type: New Feature
> Reporter: Chaitanya Mukka
> Assignee: Chaitanya Mukka
> Priority: Major
> Attachments: ClayCodeCodecDesign-20180630.pdf, HADOOP-15558.001.patch
>
>
> [Clay Codes|https://www.usenix.org/conference/fast18/presentation/vajha] are
> new erasure codes developed as a research project at Codes and Signal Design
> Lab, IISc Bangalore. A particular Clay code, with storage overhead 1.25x, has
> been shown to reduce repair network traffic, disk read and repair times by
> factors of 2.9, 3.4 and 3 respectively compared to the RS codes with the same
> parameters.
> This Jira aims to introduce Clay Codes to HDFS-EC as one of the pluggable
> erasure codec.
