How to change topology
Shinichi Yamashita 2012-10-08, 13:23
Hi,

I know that DataNode and TaskTracker must restart to change topology.
Is there the method to execute the topology change without restart of
DataNode and TaskTracker?
In other words, can I change the topology by a command?

Thanks in advance!
Shinichi
