示例1: testFailoverWhileRunningJob

@Test(timeout=60000)
public void testFailoverWhileRunningJob() throws Exception {
LOG.info("Running job failover test");
// Inspired by TestRecoveryManager#testJobResubmission
FileUtil.fullyDelete(new File("/tmp/tst"));
// start a job on jt1
JobConf job1 = new JobConf(conf);
String signalFile = new Path(TEST_DIR, "signal").toString();
UtilsForTests.configureWaitingJobConf(job1, new Path(TEST_DIR, "input"),
new Path(TEST_DIR, "output3"), 2, 0, "test-resubmission", signalFile,
