Maja Kabiljo created GIRAPH-266: ----------------------------------- Summary: Average aggregators don't calculate real average Key: GIRAPH-266 URL: https://issues.apache.org/jira/browse/GIRAPH-266 Project: Giraph Issue Type: Bug Reporter: Maja Kabiljo Assignee: Maja Kabiljo
Average aggregators calculate average on workers, and then workers' averages are sent to the master, where we actually calculate the average of averages. For example, if one worker aggregates value 2, the other values 4 and 6, and third values 8, 8 and 8, we'll get the result of 5 instead of 6. -- This message is automatically generated by JIRA.
