Q:

What happens if one Hadoop client renames a file or a directory containing this file while another client is still writing into it?

A file will appear in the name space as soon as it is created. If a writer is writing to a file and another client renames either the file itself or any of its path components, then the original writer will get an IOException either when it finishes writing to the current block or when it closes the file.
