Subject Queries on Hama Usage
Date Fri, 23 Mar 2012 10:47:33 GMT

1. 0.4.0 introduced multiple tasks on groom servers. How does the framework
send a message to a particular task on a groom server. If I am not wrong,
BSPPeer.send() sends messages to all the tasks on a groom server and it is
an overhead.

2. What is the difference between message combiners (0.4.0) and
BSPMessageBundle (0.3.0)?

3. What is the significance of BSPJob.setNumBspTask()? I thought that in
Hama the input will be split and a task will be spawned for each split in
the groom server similar to Hadoop?
