------------------------------
Issue Type: Improvement (was: Sub-task)
Parent: (was: HDFS-8031)
> Erasure Coding: create dummy coder and schema
> ---------------------------------------------
>
> Key: HDFS-9345
> URL: https://issues.apache.org/jira/browse/HDFS-9345
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Rui Li
> Assignee: SammiChen
> Labels: hdfs-ec-3.0-nice-to-have
>
> We can create dummy coder which does no computation and simply returns zero
> bytes. Similarly, we can create a test-only schema with no parity blocks.
> Such coder and schema can be used to isolate the performance issue to
> HDFS-side logic instead of codec, which would be useful when tuning
> performance of EC.
