Zhe Zhang commented on HDFS-8854:
---------------------------------
Thanks Walter for taking this task. I think we need to separate the discussion
into 2 questions:
# Whether we need an abstraction for current ECSchema + cellSize. I think we
clearly do need it. You have a good summary of the advantages:

Advantages:
1. shorter args list, cleaner code.
2. store one field in BlockInfoStriped, instead of two fields. Less memory
usage.

# Naming of the new abstraction. We probably shouldn't call it a schema,
because _schema_ is already a basic concept in codec. I think
{{ErasureCodingPolicy}} is a better name.
Maybe we can keep {{ECSchema}} class in COMMON, and refactor HDFS codes to use
{{ErasureCodingPolicy}} instead?
