Apache Curator GroupMember how to get complete set of members?
I am very new to Zookeeper so I am trying to use Curator recipes to see if I can get my pretty simple asks out of the box.
I am trying to use Curator GroupMember class/recipe in order to split workload between nodes. GroupMember start() method javadoc says "begin caching all members" - how do I request or get a notification once all members are received?
Kind of a follow-up: I've notices that sometimes my groupMember.setData() invocation throws "initial create has not been processed. Call waitForInitialCreate() to ensure" which is on PersistentNode which is not even exposed by MemberGroup.
Looks like I am really missing something about MemberGroup API :(
