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!

as well as occasional connection losses to Zookeeper. Reducing storm-server to
run one test at a time, rather than with a forkCount of 1 per core eliminates
these issues.
