Subject [jira] [Commented] (HAMA-363) Add network condition monitoring function to BSPMaster
Date Tue, 21 Jun 2011 11:51:47 GMT

    [ https://issues.apache.org/jira/browse/HAMA-363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13052498#comment-13052498

Steve Loughran commented on HAMA-363:
-------------------------------------

some more thoughts
# ganglia and collectl are the ways everyone monitors Hadoop, it would be simple and consistent
for Hama to say "this is what we target"
# the monitoring v2 stuff in 0.23 is still unstable. At some point it might be nice to make
re-usable, but it isn't there yet.

> There's few reason why this issue is important. Basically Master server should know the
status of cluster:
>  * to optimize the network usage
>  * to handle network connectivity problems
>  * to handle different network conditions
> And, I would like to see some network usage statistics.
> In this issue, we implement only basic function which is collect network usage.
