[jira] [Created] (HDFS-10091) CLONE - Remove chunkSize and initialize from erasure coder

dragon created HDFS-10091:
-----------------------------

             Summary: CLONE - Remove chunkSize and initialize from erasure coder
                 Key: HDFS-10091
                 URL: https://issues.apache.org/jira/browse/HDFS-10091
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: dragon
            Assignee: Kai Zheng
            Priority: Minor
             Fix For: HDFS-7285


Per discussion in HDFS-8347, we need to support encoding/decoding variable width units data instead of predefined fixed width like {{chunkSize}}. Have this issue to remove chunkSize in the general raw erasure coder API. Specific coder will support fixed chunkSize using hard-coded or specific schema customizing way if necessary, like HitchHiker coder.

Update: per discussion in this issue, this will also remove {{initialize}} method from erasure coders. The necessary initialization work will be done in constructors.
