Subject [jira] [Commented] (HDFS-2004) Enable replicating and pinning files to a data node
Date Tue, 07 Jun 2011 16:15:59 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2004?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13045513#comment-13045513
] 

Jason Rutherglen commented on HDFS-2004:
----------------------------------------

I think I mentioned HDFS is probably the wrong place for this, as HDFS should and basically
does allow one to implement this functionality today.  The end consumer project can easily
make the request of the name node etc.

> Some HDFS applications require that a given file is on the local DataNode.  The functionality
created here will allow pinning the file to any DataNode.
