Looks like the serialization/descrialization has a problem. If you want
to see an example of a Trove primitive map, see
LongDoubleArrayEdges.

It will be great on how you use writable maps based on Trove/ Fast
Util. Sample usage if you can share will be great.

We don't use MapWritable. Internally we have a bunch of writable
maps based on Trove or FastUtil for speed. What's your full
exception stack trace?

Hi,
I'm trying to send messages that is MapWritable
MapWritable msg = new MapWritable();
msg.put(new Text("test"), new
DoubleWritable(edgeWeightage));
sendMessage(edge.getTargetVertexId(), msg);
However, I find that this is throwing exception
(IllegalStateException)
Any inputs on what to take care while sending MapWritable
messages?
