------------------------------------------------------------

It looks like that not all Zookeeper calls are stubbed correctly. Exception are thrown when LocalFsBlobStore#prepare gets called, which calls BlobStoreUtils.createZKClient and ClusterUtils.mkStormClusterState, which then issue connection to zookeeper under the hood. I guess that the exception is suppressed implicates that this is a common issue, but may be hard to fix. [~Srdo]

> 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.
