Subject [jira] [Commented] (HAMA-439) Reorganize modules for YARN/MR-NextGen integration
Date Tue, 27 Sep 2011 16:51:45 GMT

    [ https://issues.apache.org/jira/browse/HAMA-439?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13115700#comment-13115700
] 

Vinod Kumar Vavilapalli commented on HAMA-439:
----------------------------------------------

bq. Any idea to the client package? Why do we need an extra module for the client?
I wanted to separate the user facing APIs separated from the implementation details completely,
so introduced that to include all the client side tools. In the short term, it may not be
big deal, but I can see potential benefits. We can club them later as we move through this
ticket if we don't realize any such benefit.

> I'd like to get started on HamaV2 to work with YARN/MR-nextgen.
> Here's what I think should be the module structure:
>  - *api*: Code from HamaV1 related to APIs that will be moved to this new module. This
will mainly have the BSP APIs: _BSP_, _BSPPeerInterface_ and all the related records like
_BSPMessage_, _BSPMessageBundle etc.
>  - *core*: Current/HamaV1 server code. Will have the current _BSPMaster_/_GroomServer_
infrastructure. We should probably rename it to {{classic-server}} or something similar.
>  - *server*: New Hama server implementation to work with YARN. Will have _BSPApplicationMaster_,
_BSPTask_ and related code.
>  - *client*: Code from HamaV1 related to client that will be moved to this new module.
This will mainly have the client-submission classes/interfaces like _BSPJob_, _BSPJobClient_,
_JobStatus_ etc. It will be configurable to either run with the classic-server implementation
or with YARN.
> There will not be any package changes but only code-moves across modules, so we will
be backwards compatible.
> How does it look? Any thoughts/suggestions?
