             Summary: HDFS Erasure Coding doc should state its currently supported erasure coding policies
                 Key: HDFS-10910
                 URL: https://issues.apache.org/jira/browse/HDFS-10910
             Project: Hadoop HDFS
          Issue Type: Improvement
    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.
