AnonHxy opened a new pull request, #19537: URL: https://github.com/apache/pulsar/pull/19537
### Motivation If we delete the ledger file from the bookkeeper, we could open the ledger but will read fail. Then if we restart the broker server to trigger ManagedLedgerImpl initializes, the `AppendIndexMetadataInterceptor` will try to read the LAC position to recovery the index, which will cause the topic creating fail, see line425 https://github.com/apache/pulsar/blob/cb306c8e6c5da3a05ea312a5e5746eb178d9ab10/managed-ledger/src/main/java/org/apache/bookkeeper/mledger/impl/ManagedLedgerImpl.java#L421-L427 To fix it , we should do the same action as line434~line435 if `BKNoSuchLedgerExistsException` thrown. https://github.com/apache/pulsar/blob/cb306c8e6c5da3a05ea312a5e5746eb178d9ab10/managed-ledger/src/main/java/org/apache/bookkeeper/mledger/impl/ManagedLedgerImpl.java#L432-L436 ### Modifications Removing the ledger from `ManagedLedgerImpl` and call `initializeBookKeeper()` if `managedLedgerInterceptor.onManagedLedgerLastLedgerInitialize` throws `BKNoSuchLedgerExistsException`, instead of callback fail. ### Verifying this change - [x] Make sure that the change passes the CI checks. - Add UT `org.apache.pulsar.broker.service.PersistentTopicTest#testLastEntryReadErrorWhenInitWithManagedLedgerInterceptor` ### Documentation <!-- DO NOT REMOVE THIS SECTION.

GitHub Actions provides separate quota for pull requests that are executed in a forked repository. The tests will be run in the forked repository until all PR review comments have been handled, the tests pass and the PR is approved by a reviewer. --> -- This is an automated message from the Apache Git Service.
