---------------------------------------
Summary: Yarn registry to create Curator binding on demand
Key: HADOOP-16034
URL: https://issues.apache.org/jira/browse/HADOOP-16034
Project: Hadoop Common
Issue Type: Improvement
Components: registry
Affects Versions: 3.1.1
Reporter: Steve Loughran
Assignee: Steve Loughran
If enough slider worker nodes are created, and then each create a Registry
client, then ZK can overload even when they aren't making calls of the
registry. Why so? Because curator gets started up on serviceStart(), even when
not used.
Proposed fix: make it on-demand on use of a ZK read/write operation
