Subject [jira] [Commented] (GIRAPH-10) Aggregators are not exported
Date Tue, 15 Nov 2011 07:43:51 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-10?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13150287#comment-13150287

Arun Suresh commented on GIRAPH-10:
-----------------------------------

wrt my previous comment, I meant Aggregators MUST be persisted at the end of EACH superstep
rather than giving the user control over the frequency. One thought thought.. If we assume
the Aggregator value is stored in the Zookeeper server reliably for the duration of the Job,
why persist it in the first place. I guess the only reason would be that the actually artifact
of interest after a Job has been run is the Aggregator value rather than the state of the
Vertices.

> Currently, aggregator values cannot be saved after a Giraph job.  There should be a way
to do this.
