Lantao Jin created MAPREDUCE-7025: ------------------------------------- Summary: Avg and Max of memory could be record in TaskCount Key: MAPREDUCE-7025 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7025 Project: Hadoop Map/Reduce Issue Type: Improvement Reporter: Lantao Jin Assignee: Lantao Jin
MapReduce Counter is very helpful tool to do statistics, analysis and tuning in industry. One popular way is analysing job historical status of running to optimise continuously. But when the job completed, the memory usage in counter is a snapshot value {{PHYSICAL_MEMORY_BYTES}}. So if we can record the average value and the max value instead of the last snapshot value, it could be much helpful. If you think it' ok. I will contribute the code. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-dev-h...@hadoop.apache.org
