> When I ran DISTCP to copy files from one dfs to another, I noticed that some
> mappers got killed due to failing to report status for 606 seconds.
> I noticed that the mappers try to make a progress report for every 32MB
> copied. A better way to ensure progress is to use a time interval since last
> report.
