Zhengdai Hu commented on STORM-3128: ------------------------------------ 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. > Connection refused error in AsyncLocalizerTest > ---------------------------------------------- > > Key: STORM-3128 > URL: https://issues.apache.org/jira/browse/STORM-3128 > 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. > {noformat} > 2018-06-27 13:05:28.005 [main-SendThread(localhost:2181)] INFO > org.apache.storm.shade.org.apache.zookeeper.ClientCnxn - Opening socket > connection to server localhost/0:0:0:0:0:0:0:1:2181.
