Subject [jira] [Commented] (HDFS-7349) Support DFS command for the EC encoding
Date Thu, 05 Feb 2015 02:38:35 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7349?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14306525#comment-14306525

Kai Zheng commented on HDFS-7349:
---------------------------------

OK no problem. I'm working on the way from low level coders to upper level codecs in relevant
JIRAs, which will make schemas configurable, pluggable and workable, having the two predefined
as system defaults. Meanwhile, we may have the schemas with their parameters hard-coded as
you previously suggested in places they're needed and later I will resolve them.
