------------------------------------------------------------
I added the stack trace of the exception that crashed the test. It looks like
other build failures are likely to be caused by the same error. It's really
strange though. [~Srdo]

> Project: Apache Storm
> Issue Type: Bug
> Components: storm-server
> Affects Versions: 2.0.0
> Reporter: Zhengdai Hu
> Priority: Major
>
> In AsyncLocalizerTest testKeyNotFoundException, a localBlobStore is created
> and tries but failed to connect to zookeeper due to connection error. I'm not
> sure if this compromises the test even though it is passed after connection
> retry timeout. But it's nice to keep in mind.
