Subject Restart node => hinted handoff flood
Date Thu, 04 Jul 2013 14:43:56 GMT

Using C*1.2.2 12 EC2 xLarge cluster.

When I restart a node, if it spend a few minutes down, when I bring it up,
all the cpu are blocked at 100%, even once compactions are disabled,
inducing a very big and intolerable latency in my app. I suspect Hinted
Handoff to be the cause of this. disabling gossip fix the problem, enabling
it again brings the latency back (with a lot of gc, dropped messages...).

Is there a way to disable HH ? Are they responsible for this issue ?

I currently have this node down, any fast insight would be appreciated.
