Hello,
I run my own program in Hama.I use the function
sendMessageToNeighbors() to send messages to neighbors of each vertex.But I get
the following errors.
14/01/08 14:49:46 ERROR bsp.LocalBSPRunner: Exception during BSP
execution!
java.lang.IllegalArgumentException: Messages must never be behind the vertex in
ID! Current Message ID: 2 vs. 5

I'm sure that all edges point to existing vertices.So I'm all adrift
about this error.Could you help me to solve this problem?Thank you a lot.
Best wishes.
