> When DFSOutputStream writes to multiple blocks, it closes only the socket opened for
the last block. When it is done with writing to one block it should close the socket.
> I noticed this when I was fixing HADOOP-3067. After fixing HADOOP-3067, there were still
a lot of sockets open (but not enough to fail the tests). These sockets were used to write
to blocks.
