Date Tue, 06 Oct 2009 01:29:31 GMT

     [ https://issues.apache.org/jira/browse/HDFS-654?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Suresh Srinivas updated HDFS-654:
---------------------------------

    Attachment: hdfs-654.5.patch

New patch with deprecated methods as suggested by Konstantin. In three places deprecated warnings
are suppressed. First one in FSEditLog which calls deprecated rename to replay a change recorded
in the edits. Two others are in tests.

> New rename functionality with different semantics to overwrite the existing destination
was introduced for use in FileContext. Currently the default implementation in FileSystem
is not atomic. This change implements atomic rename operation for use by FileContext.
