Example 1 with LockClosedException

use of org.apache.distributedlog.lock.LockClosedException in project bookkeeper by apache.

the class TestAsyncReaderLock method testReaderLockFutureCancelledWhileWaiting.

@Test(timeout = 60000)
public void testReaderLockFutureCancelledWhileWaiting() throws Exception {
    String name = runtime.getMethodName();
    DistributedLogManager dlm0 = createNewDLM(conf, name);
    BKAsyncLogWriter writer = (BKAsyncLogWriter) (dlm0.startAsyncLogSegmentNonPartitioned());
    writer.write(DLMTestUtil.getLogRecordInstance(1L));
    writer.write(DLMTestUtil.getLogRecordInstance(2L));
    writer.closeAndComplete();
    DistributedLogManager dlm1 = createNewDLM(conf, name);
    CompletableFuture<AsyncLogReader> futureReader1 = dlm1.getAsyncLogReaderWithLock(DLSN.InitialDLSN);
    AsyncLogReader reader1 = Utils.ioResult(futureReader1);
    DistributedLogManager dlm2 = createNewDLM(conf, name);
    CompletableFuture<AsyncLogReader> futureReader2 = dlm2.getAsyncLogReaderWithLock(DLSN.InitialDLSN);
    try {
