Subject [jira] [Commented] (HDFS-4711) Can not change replication factor of file during moving or deleting.
Date Thu, 18 Apr 2013 18:58:13 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13635530#comment-13635530

Vladimir Barinov commented on HDFS-4711:

-setrep works well but it was confusing when move does not supported it and usage tells nothing
about it. Probably I should change ticket to "new feature" or "improvement"?

>             Project: Hadoop HDFS
>          Issue Type: Bug
>    Affects Versions: 2.0.0-alpha
>            Reporter: Vladimir Barinov
>            Priority: Minor
> I don't know is it a feature or a bug. 
> According to hdfs dfs -help we can use key -D to set specific options for action;
> When we copying or uploading file to hdfs we can override replication factor with -D
dfs.replication=N. That's works well.
> But it doesn't work for moving or removing(to trash) file.
> Steps to reproduce:
> Uploading file
> hdfs dfs -put somefile /tmp/somefile
> Copying with changing replication:
> hdfs dfs -D dfs.replication=1 -mv /tmp/somefile /tmp/somefile2
> hadoop version:
> Hadoop 2.0.0-cdh4.1.2
