Subject [jira] [Commented] (HDFS-11082) Erasure Coding : Provide replicated EC policy to just replicating the files
Date Wed, 16 Aug 2017 01:09:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11082?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16128174#comment-16128174
] 

Andrew Wang commented on HDFS-11082:
------------------------------------

Thanks for revving Sammi, only a single nit, looks good otherwise:

* We should update the help to make it clear that -policy and -replicate are optional arguments,
e.g.

{noformat}
         [-setPolicy -path <path> [-policy <policyName>] [-replicate]]
{noformat}

Please file and link the follow-on JIRA for here for tracking too. Great work!

> The idea of this jira is to provide a new {{replicated EC policy}} so that we can override
the EC policy on a parent directory and go back to just replicating the files based on replication
factors.
