Subject [jira] [Commented] (HAMA-479) Add Counters to Hama Jobs
Date Mon, 28 Nov 2011 08:32:39 GMT

    [ https://issues.apache.org/jira/browse/HAMA-479?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13158279#comment-13158279
] 

Thomas Jungblut commented on HAMA-479:
--------------------------------------

Should we provide both, enums and strings as keys for counters?
At the end they are going to be both in a map as a string I guess, so we should support both
of them.

> We should add counters for each Hama job.
> We want to add message counters (bytes transfered, local messages sent, outward messages
sent, time in sync etc.), for the last superstep and summed up for all supersteps. 
> It should be as simple as the from Hadoop provided mechanism with enums.
> We could eventually use zookeeper instead of the jobreport.
> For the SSSP Example it should be useful that the last superstep counters are always
in sync in each task after a superstep. == After barrier left, query zookeeper for the values.
