Subject [jira] Commented: (HADOOP-2078) Name-node should be able to close empty files.
Date Fri, 19 Oct 2007 16:58:50 GMT

Konstantin Shvachko commented on HADOOP-2078:
---------------------------------------------

I don't see any tests with empty files, do you? We always write something into it before closing.
Checking pendingFile is redundant, since if fileBlocks is null then pendingFile is always
null as well.

> Name-node should be able to close empty files.

> When I try to close an empty file, the name-node throws an exception "Could not complete
write to file" 
> and issues a warning "NameSystem.completeFile: failed to complete".
> I don't see any reason why empty files should not be allowed.
