Duo Zhang updated HBASE-15495:
------------------------------
    Attachment: HBASE-15495.patch

It is not easy to test this problem because we do not have the reference of client side connection if connect failed. And datanode will close the connection when we call recoverFileLease. But you can find something in log that with old implementation, the datanode connection is closed when doing recoverFileLease, and with this patch, the datanode connection is closed because of EOF which means the connection is closed by remote side.

Anyway, I added a testcase to cover the connect failed condition.
