Subject Re: What is listEndpointsPendingHints?
Date Thu, 28 Nov 2013 06:08:50 GMT
Tom,

Here is the definition
List all the endpoints that this node has hints for, and count the number
of hints for each such endpoint.

Returns:map of endpoint -> hint count


I would suggest looking at at the gossipinfo to validate if there are any
nodes which have that token value. If there is ( there should be since its
storing hints ) you should assassinate the node and you should be on your
way.

Thanks
Rahul
