Subject [jira] [Commented] (HDFS-12395) Support erasure coding policy operations in namenode edit log
Date Mon, 18 Sep 2017 20:23:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12395?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16170622#comment-16170622
] 

Andrew Wang commented on HDFS-12395:
------------------------------------

[~kihwal] EC added LV -64 when the branch was merged. Since we've been in alpha up to now,
the thinking was that we can piggyback on the existing EC layout version since we don't need
to support upgrade from alpha->beta.
