Subject [jira] [Commented] (HDFS-7859) Erasure Coding: Persist EC schemas in NameNode
Date Tue, 07 Apr 2015 07:53:13 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7859?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14482766#comment-14482766

Vinayakumar B commented on HDFS-7859:
-------------------------------------

bq. When we have this work done, we may also have the idea about how to serialize/deserialize
an EC schema in RPC between NameNode and client/DataNode
This is included in the latest patch provided in HDFS-8023.

> In meetup discussion with [~zhz] and [~jingzhao], it's suggested that we persist EC schemas
in NameNode centrally and reliably, so that EC zones can reference them by name efficiently.
