------------------------------------------
Summary: Correct DataNode.getChildren() inconsistent behavior.
Key: ZOOKEEPER-2680
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2680
Project: ZooKeeper
Issue Type: Bug
Components: server
Affects Versions: 3.5.1, 3.4.9
Reporter: Mohammad Arshad
Assignee: Mohammad Arshad
DataNode.getChildren() API returns null and empty set if there are no children
in it depending on when the API is called. DataNode.getChildren() API behavior
should be changed and it should always return empty set if the node does not
have any child
*DataNode.getChildren() API Current Behavior:*
# returns null initially
When DataNode is created and no children are added yet, DataNode.getChildren()
returns null
# returns empty set after all the children are deleted:
created a Node
add a child
delete the child
DataNode.getChildren() returns empty set.
After fix DataNode.getChildren() should return empty set in all the above cases.
