Subject [jira] Commented: (HDFS-1675) Transfer RBW between datanodes
Date Wed, 09 Mar 2011 05:46:59 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1675?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13004377#comment-13004377

Hairong Kuang commented on HDFS-1675:
-------------------------------------

I feel that it is better to put RBW in tmp first and then move to rbw when copy is done. Otherwise,
if there is an error during copy then copy aborts, lease recovery will make a wrong decision
deciding replica length and then truncate visible bytes.
