cannot reproduce the issue on my local. When MetadataStoreConfig#metadataStoreName is a empty string, this issue happens, but I've checked everywhere, the field must not be empty

@tjiuming This was fairly easy to reproduce with @Test(invocations = 100). I created a fix in #19329. Please review

[lhotari]

The problem remains. Example failure: https://github.com/apache/pulsar/actions/runs/4072071397/jobs/7016199219#step:11:1265

There's more debug logging after the #19329 changes so it might be easier to find out what is going on.
