> ------------------------------------------------------------------------------------
>
> Key: HDFS-10910
> URL: https://issues.apache.org/jira/browse/HDFS-10910
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: documentation, erasure-coding
> Affects Versions: 3.0.0-alpha1
> Reporter: Wei-Chiu Chuang
>
> While HDFS Erasure Coding doc states a variety of possible combinations of algorithms, block group size and cell size, the code (as of 3.0.0-alpha1) allows only three policies: RS_6_3_SCHEMA, RS_3_2_SCHEMA and RS_6_3_LEGACY_SCHEMA. All with default cell size. I think this should be documented.
