> This seems to be because the LocalFsBlobStoreTest is mocking NimbusInfo, and
> the properties on that object aren't stubbed. Occasionally the test will try
> to e.g. do a string contains with the null value from the stub, which throws
> an NPE. Since NimbusInfo is just a POJO, I don't see why we would need to
> mock it, we could just supply dummy values.
> I'm also seeing test failures on nearly every run locally, seemingly due to
> interference between the tests. Example:
> {code}
> testLocalTransport(org.apache.storm.MessagingTest) Time elapsed: 8.197 sec
> <<< ERROR!
> java.lang.RuntimeException: java.lang.RuntimeException: No nimbus leader
> participant host found, have you started your nimbus hosts?
