Sanjay Radia commented on HDFS-487: ----------------------------------- Are you proposing a UID so that fileIds can be global across NN volumes? Isn't an ID unique to the NN volume sufficient for our needs? > 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 > Attachments: fileid1.txt > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
