How can i automatically clean it, for example, if log older then 7 days - its must be retain from local.

@Yuriy_but For CDH related service like Yarn you can configure NodeManager Maximum Log File Backups in Service Configuration but if these are some custom logs then I would say setup a cron job to delete these periodically. 


Cheers!
