Hello, I want to ask how to parallel processing, a binary tree has two servers, I'd like to, respectively, each dealing with binary tree around the subtree, in their respective server traversal each subtree of all child nodes,
Such as:
A
B C
D, E, F, G

The main output A
Server a1 output D B E
Server a2 output C F G


Could you tell me how to do this? Use hadoop can? Trouble explain in detail, thank you,

Hadoop parallel processing is now the data is split, and then shuffle the merge combine, but the distribution of task and not the procedure control, the output of the results is focused, because of the cluster nodes to Mr Program is blocked
