Subject [jira] [Commented] (HDFS-11606) Add CLI cmd to remove an erasure code policy
Date Tue, 20 Jun 2017 00:47:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11606?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16055005#comment-16055005

Kai Zheng commented on HDFS-11606:

The latest patch LGTM and +1. Thanks Tim! We might get rid of the {{removedPoliciesByName}}
map in the {{ErasureCodingPolicyManager}} later when following on the required fsimage/editlog

Will get it in tomorrow if no further comments.
