> DFSTestUtil creates files with random sizes, but there is no minimum size. So, sometimes,
it can make a file with length 0. This will cause tests that use this functionality to fail
- for example, TestListCorruptFileBlocks assumes that each of the created files has at least
one block. We should add a minSize parameter to prevent this.
