示例1: testLocate
import org.apache.hadoop.io.file.tfile.TFile.Reader.Location; //导入依赖的package包/类
public void testLocate() throws IOException {
if (skip)
return;
writeRecords(3 * records1stBlock);
Reader reader = new Reader(fs.open(path), fs.getFileStatus(path).getLen(), conf);
Scanner scanner = reader.createScanner();
Location loc2 =
locate(scanner, composeSortedKey(KEY, 3 * records1stBlock, 2)

Location locLastIn1stBlock =
locate(scanner, composeSortedKey(KEY, 3 * records1stBlock,
records1stBlock - 1).getBytes());

Location locX = locate(scanner, "keyX".getBytes());
Assert.assertEquals(scanner.endLocation, locX);
scanner.close();
reader.close();
