@Test
public void testGetBlockLocations() throws IOException {
Path targetFilePath = new Path(targetTestRoot,"data/largeFile");
FileContextTestHelper.createFile(fcTarget, targetFilePath, 10, 1024);
Path viewFilePath = new Path("/data/largeFile");

BlockLocation[] viewBL = fcView.getFileBlockLocations(viewFilePath,
0, 10240+100);
Assert.assertEquals(SupportsBlocks ? 10 : 1, viewBL.length);
