dhruba borthakur commented on HADOOP-2078:
------------------------------------------
Good catch. I wonder why our unit test does not catch this one. There is a test
that checks zero-length files.
Shouldn't the test be if (fileBlocks == null || pendingFile == null) { throw
exception() }?
> 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.
