[jira] [Commented] (HDDS-8716) ReplicationFactor will be ONE when distcp hdfs ec file to ozone

["Hongbing Wang (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HDDS-8716?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17728287#comment-17728287 ] 

Hongbing Wang commented on HDDS-8716:
-------------------------------------

distcp -p or -pr will preserve replication number. HDFS ec rep is 1.
In this case, it may be better for ozone to use the default replicationFactor if ozone dir does not has ec policy. 

ONE replicationFactor maybe risks.
