Subject [jira] [Commented] (HDFS-7866) Erasure coding: NameNode manages EC schemas
Date Fri, 10 Apr 2015 13:09:16 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7866?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14489577#comment-14489577

Kai Zheng commented on HDFS-7866:
---------------------------------

bq.Shall I raise a separate sub-task and start exploring it more?
I just checked HDFS-7349. Yes we would need a separate issue to add {{refreshECSchemas}} command.
It can co-work with this issue and HDFS-8112. Please go ahead, thanks.

> This is to extend NameNode to load, list and sync predefine EC schemas in authorized
and controlled approach. The provided facilities will be used to implement DFSAdmin commands
so admin can list available EC schemas, then could choose some of them for target EC zones.
