Review Comment:
Ok, I found the problem. In the test, it may kill the follower auditor, the
follower auditor can't be aware of the close behavior, because the follower
auditor is blocked due to waiting leader shutdown.
### The reproduce code:
```
public TestAutoRecoveryAlongWithBookieServers() throws Exception {
super(2);
setAutoRecoveryEnabled(true);
Class.forName("org.apache.pulsar.metadata.bookkeeper.PulsarMetadataClientDriver");
Class.forName("org.apache.pulsar.metadata.bookkeeper.PulsarMetadataBookieDriver");
}
@Test
public void testAutoRecoveryAlongWithBookieServers() throws Exception {
BookieId firstBookie = getBookie(0);
BookieId secondBookie = getBookie(1);
// killBookie(firstBookie);
Auditor auditor = getAuditor(10000, TimeUnit.MILLISECONDS);
Field bookieIdentifier =
auditor.getClass().getDeclaredField("bookieIdentifier");
bookieIdentifier.setAccessible(true);
String auditorId = (String) bookieIdentifier.get(auditor);
System.out.println("kill:" + auditorId);
if (firstBookie.toString().equals(auditorId)) {
killBookie(secondBookie);
} else {
killBookie(firstBookie);
}
Thread.sleep(10000);
if (firstBookie.toString().equals(auditorId)) {
killBookie(firstBookie);
} else {
killBookie(secondBookie);
}
}
```
