Description
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.

I managed to track down the source where the exception is thrown, but it's really strange that this is called by a StormTimer inside Supervisor, which is not declared anywhere in this test. I'm completely lost by now.
