Raghu Angadi commented on HDFS-487:
-----------------------------------


Given that there is mapping from id to the file, I am not sure if it really 
works like an id. Can you explain the use case bit more? (I haven't read the 
patch for pluggable block placement)

When I first read the title of the jira, thought this might be about file 
handles...

> HDFS should expose a fileid to uniquely identify a file

> 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.
