1. I checked the code according to the above error log and found that it may
be repeated execution of `PersistentTopic::delete `. This error may be reported
when this method is executed multiple times.
2. According to the above reproduction, I tried to reproduce several times,
but I didn't get the above exception, instead, I got another exception:
`org.apache.pulsar.metadata.api.MetadataStoreException`
The error is as follows:
