[GitHub] storm issue #2517: [STORM-2901] Reuse ZK connection for getKeySequenceNumber

    Nice finding!
    
    Btw, according to Curator web site, each process (nimbus, supervisor, worker, etc.) can share singleton curator framework instance since it's thread-safe.
    
    http://curator.apache.org/curator-framework/
    
    > CuratorFrameworks are allocated using the CuratorFrameworkFactory which provides both factory methods and a builder for creating instances. IMPORTANT: CuratorFramework instances are fully thread-safe. You should share one CuratorFramework per ZooKeeper cluster in your application.
    
    We are using Curator 4.0 both master and 1.x branch, hence we are good to apply this.
