[jira] Created: (HDFS-487) HDFS should expose a fileid to uniquely identify a file

HDFS should expose a fileid to uniquely identify a file
-------------------------------------------------------

                 Key: HDFS-487
                 URL: https://issues.apache.org/jira/browse/HDFS-487
             Project: Hadoop HDFS
          Issue Type: New Feature
            Reporter: dhruba borthakur
            Assignee: dhruba borthakur


HDFS should expose a id that uniquely identifies a file. This helps in developing  applications that work correctly even when files are moved from one directory to another. A typical use-case is to make the Pluggable Block Placement Policy (HDFS-385) use fileid instead of filename.
