Subject [jira] Updated: (HDFS-654) HDFS needs to support new rename introduced for FileContext
Date Mon, 05 Oct 2009 21:05:31 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-654.3.patch

New patch incorporates all the comments from Konstantin, except deprecation. After hudson
tests to confirm the patch is good, I will attach another patch with old Rename deprecated.
This will result in warnings. These need to be ignored to submit the patch.

> 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.
