> Implement another Reed-Solomon coder in pure Java
> -------------------------------------------------
>
> Key: HADOOP-12041
> URL: https://issues.apache.org/jira/browse/HADOOP-12041
> Project: Hadoop Common
> Issue Type: Sub-task
> Reporter: Kai Zheng
> Assignee: Kai Zheng
> Attachments: HADOOP-12041-v1.patch, HADOOP-12041-v2.patch,
> HADOOP-12041-v3.patch
>
>
> Currently existing Java RS coders based on {{GaloisField}} implementation
> have some drawbacks or limitations:
> * The decoder computes not really erased units unnecessarily (HADOOP-11871);
> * The decoder requires parity units + data units order for the inputs in the
> decode API (HADOOP-12040);
> * Need to support or align with native erasure coders regarding concrete
> coding algorithms and matrix, so Java coders and native coders can be easily
> swapped in/out and transparent to HDFS (HADOOP-12010);
> * It's unnecessarily flexible but incurs some overhead, as HDFS erasure
> coding is totally a byte based data system, we don't need to consider other
> symbol size instead of 256.
> This desires to implement another RS coder in pure Java, in addition to the
> existing {{GaliosField}} from HDFS-RAID. The new Java RS coder will be
> favored and used by default to resolve the related issues. The old HDFS-RAID
> originated coder will still be there for comparing, and converting old data
> from HDFS-RAID systems.
