Raghu Angadi commented on HADOOP-5581:
--------------------------------------

+1.

Regd the contract, it needs to be added to ClientProtocol.getBlockLocations() and FNF is not the only exception. It is ok for now.

> When trying to open a file that does not exist for read, libhdfs prints an error out along the line of "Cannot open file <filename>".
> I believe it should be throwing the FileNotFoundException instead.  This would allow us to correctly set the errno and more naturally give the errors to the C-based clients.
