Subject [jira] [Commented] (HDFS-8382) Remove chunkSize parameter from initialize method of raw erasure coder
Date Tue, 19 May 2015 21:05:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14551221#comment-14551221

Tsz Wo Nicholas Sze commented on HDFS-8382:
-------------------------------------------

We should remove all the initialize methods, pass the parameter via constructors and change
all the fields to final.

> 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.
