Subject [jira] [Commented] (HAMA-258) Design a input and output system
Date Sun, 25 Sep 2011 20:07:26 GMT

    [ https://issues.apache.org/jira/browse/HAMA-258?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13114351#comment-13114351

Thomas Jungblut commented on HAMA-258:
--------------------------------------

Let's summarize a bit:

- Input and InputFormat are managed the same way as it is in Hadoop.
- Input send as initial messages
- Coordination between client and BSP 
- Input has random read feature

*Input and InputFormat are managed the same way as it is in Hadoop.*
& *Input send as initial messages*

This sounds clear, how do we split the data? And how does this going to be send to the tasks
as initial messages?

* Coordination between client and BSP *
Not a part of the I/O System, is it? Sounds like a more general synchronization between the
BSPClient and our BSPMaster.

* Input has random read feature *
This is great, but a lot of work? / Additional feature. 

What are your ideas Edward?
