Alexey,

My initial approach was to put reference into NodeLocalMap after "start"
method since I saw no other possibility to do that since I was a little bit
bit confused of - https://issues.apache.org/jira/browse/IGNITE-1018.
But then I tried to go with LifecycleBean but with AFTER_NODE_START.

So, could you please clarify do I know can be coupled to BEFORE_NODE_START?

And with regards to:

>>  If this is a requirement for you, you can put a simple CountDown latch
to the NodeLocalMap, wait for it in an EntryProcessor and release it once
the NodeLocalMap is in a consistent state.

Here the question still remains the same - Where/when it is safe to put
this CountDown latch into NodeLocalMap?

Thanks,
