Konstantin Boudnik updated HDFS-812:
------------------------------------

    Attachment: HDFS-812.patch

I believe, this test version better reflects the expected reaction of 
FSnamesystem in case of 0 blocks length. Lease needs to be removed and file to 
be closed.

> FSNamesystem#internalReleaseLease will throw ArrayIndexOutOfBoundException on 
> an empty file's lease recovery

> {{FSNamesystem.internalReleaseLease()}} uses the result of 
> {{iFile#numBlocks();}} call to get a number of an under construction file's 
> blocks. {{numBlock()}} can return 0 if the file doesn't have any blocks yet. 
> This will cause {{internalReleaseLease()}} to throw 
> ArrayIndexOutOfBoundException
