> 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.
