Review comment:
       Sorry, totally missed this was an integration test - dunno how that 
happened.  To confirm your conjecture above, yes my test sleeps because it has 
to have a metadata update, with partial info, to repro the failure, just as 
yours does.

>  *InternalFunctionInvocationTargetException: Multiple target nodes found for 
> single hop operation* occurs on native client when executing function in a 
> single hop manner for all buckets during the period when client bucket 
> metadata doesn't contain all buckets locations.
> Java client in this case executes functions in non single hop manner until it 
> receives locations of all buckets on servers. The solution in native client 
> would be to implement the same handling as in java client.
