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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
