Returns: Array |
Nodes can be in clusters. Clusters can also be in clusters. This function returns and array of
- nodeIds
- showing where the node is.
Example:
+ nodeIds showing where the node is.
+
+
+ If any nodeId in the chain, especially the first passed in as a parameter, is not present in
+ the current nodes list, an empty array is returned.
+
+
Example:
cluster 'A' contains cluster 'B',
cluster 'B' contains cluster 'C',
cluster 'C' contains node 'fred'.
