[jira] [Updated] (HADOOP-11740) Combine erasure encoder and decoder
interfaces
[ https://issues.apache.org/jira/browse/HADOOP-11740?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Zhe Zhang updated HADOOP-11740:
-------------------------------
Attachment: HADOOP-11740-000.patch
This initial patch simply removes {{ErasureEncoder}} and {{ErasureDecoder}}. I think the following further simplifications are possible:
# We can get rid of {{ErasureCoder}} since it has a single subclass now ({{AbstractErasureCoder}}
# Similarly, maybe we can get rid of {{ErasureCodingStep}} since {{AbstractErasureCodingStep}} provides enough abstraction anyway
# If {{ECBlockGroup}} can provide erased indices, we can further combine encoding and decoding classes
> Combine erasure encoder and decoder interfaces
