Is this second issue new bug or it is feature because of default block size?
Question also is, if file can be copied partially or operation should be

How reproducible:
100%

Actual results:
There is Input/output error. 

Expected results:
Result of exceeding quota should be at least meaningful error message. If this is functionality bug, then the file should not been copied at all because there is no space. I'll check it on hdfs.
