Tom,

Here is the definition=A0
List all the endpoints that this n= ode 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 n= odes which have that token value. If there is ( there should be since its s= toring hints ) you should assassinate the node and you should be on your wa= y. =A0=A0

Thanks
Rahul

It suggests that there are pending hints, but the= org.apache.cassandra.internal:type=3DHintedHandoff mbean provides these fi= gures:

TotalBlockedTasks =3D 0;
Cur= rentlyBlockedTasks =3D 0;
CoreThreads =3D 2;
MaximumThreads =3D 2;
=
ActiveCount =3D 0;
PendingTasks =3D 0;
Com= pletedTasks =3D 0;

I'm wondering wha= t it means that it returns a value, and what this value is? It looks like a= token, but it's not one of the tokens of my nodes.

The reason I'm looking into this is that my cluster= suffering every now and then from never ending (dead) hinted handoff tasks= , resulting in a flooding of hints on the node.

Thanks,
Tom
