Arun C Murthy commented on HADOOP-2208: --------------------------------------- bq. One really simple option is to to add a Counters.clear method and call it from TaskStatus.clearStatus, this will ensure that only updated counters are sent in every hearbeat. I jumped to hasty conclusion. Forget it, won't work. > Reduce frequency of Counter updates in the task tracker status > -------------------------------------------------------------- > > Key: HADOOP-2208 > URL: https://issues.apache.org/jira/browse/HADOOP-2208 > Project: Hadoop > Issue Type: Improvement > Reporter: Amareshwari Sri Ramadasu > Assignee: Amareshwari Sri Ramadasu > > Currently, We have counter updates from task tracker to job tracker on every > heartbeat. Both counter name and the values are updated for every heartbeat. > This can be improved by sending names and values for the first time and only > the values after that. > The frequency can be reduced by doing update only when the counters got > changed. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
