-----------------------------------
Summary: Share CuratorFramework instance in a process
(daemons/worker)
Key: STORM-2938
URL: https://issues.apache.org/jira/browse/STORM-2938
Project: Apache Storm
Issue Type: Improvement
Components: storm-client, storm-server
Reporter: Jungtaek Lim
According to Curator web site, each process (nimbus, supervisor, worker, etc.)
can share singleton curator framework instance per ZK cluster since it's
thread-safe.
[http://curator.apache.org/curator-framework/]
{quote}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.
{quote}
We are using Curator 4.0 both master and 1.x branch, hence we are good to apply
this.
We already applied this for Nimbus via STORM-2901. This issue is to track the
efforts for other processes.
