[ https://issues.apache.org/jira/browse/CHUKWA-87?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ari Rabkin updated CHUKWA-87:
-----------------------------
Component/s: Data Processors
> Rewrite all rolling classes
> ---------------------------
>
> Key: CHUKWA-87
> URL: https://issues.apache.org/jira/browse/CHUKWA-87
> Project: Hadoop Chukwa
> Issue Type: Improvement
> Components: Data Processors
> Reporter: Jerome Boulon
> Assignee: Jerome Boulon
>
> There's a dependency between Hourly and Daily rolling.
> This should be simplified to only be a generic compacter.
> The compacter should run whenever there's more than xx spills files in the stream directory and this could happen any time during the day.
> This may implies flattering the stream hierarchy but the logic for that is only on the 2 rolling classes and the MoveToRepo class.
> The compacter should be able to get the list of files, compact them, put the new file in place and removed the one that have been part of the compacter M/R job.
> The compacter will be a daemon process that will always run in background.
