Date Wed, 23 Jun 2010 05:30:50 GMT

    [ https://issues.apache.org/jira/browse/HDFS-650?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12881552#action_12881552

Gokul commented on HDFS-650:
----------------------------

At this point, I could provide some information is that the user request the APPEND operation
before the file is not closed.

So this issue is there only in this scenario?? (When user tries to append before closing the
file)
