[jira] [Commented] (HAMA-258) Design a input and output system
[ 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?
