> Add more Java Unit Test Coverage for the feature HDFS-3701 where the file is opened for
writing, the DFSClient calls one of the datanode owning the last block to get its size, and
if this datanode is dead then test for if socket IO Exception is thrown. Add a unit test case
to write to a file, shutdown the datanodes, and then try to read from the file and expect
an IO Exception. On branch 1 it should throw the IO Exception as expected.
