Ari Rabkin commented on CHUKWA-204:

Am I right in thinking this is a 0.2 issue, not a 0.1.2 issue?

> Agent side file expiration/removal
> ----------------------------------
>                 Key: CHUKWA-204
>                 URL:
>             Project: Hadoop Chukwa
>          Issue Type: New Feature
>          Components: data collection, Data Processors
>            Reporter: Jerome Boulon
>            Priority: Critical
> We have a shell script in order to expire files older than x days.
> The idea is to move this to ChukwaAgent in order to reduce the number of daemon running
and the overall complexity.
> This could be done in a background/low priority Cleanup Thread inside the agent.
> The input should be a configuration file with:
> - path + fileName + regex (similar to the expiration in our Log4J appender)
> - number of days (last accessed/modified? date)
> The initial version could be as simple as this but a more advanced version will be needed.
> The advanced version should be able to track data completeness based on CHUKWA-203 and
only remove file that has been completely sent over or generate alerts.
