-----------------------------------
Resolution: Not a Problem
> Add File Count Threshold to HBCK
> --------------------------------
>
> Key: HBASE-3319
> URL: https://issues.apache.org/jira/browse/HBASE-3319
> Project: HBase
> Issue Type: Improvement
> Components: util
> Reporter: Nicolas Spiegelberg
> Priority: Minor
>
> A useful check to add to HBCK is a way to estimate the max # of files that a
> cluster should have and raise a warning/error if the file count goes above
> that threshold. We ran into an issue this week where our ".oldlogs" folder
> filled up to 100k files because 'hbase.master.logcleaner.maxdeletedlogs" was
> set too low. We found this because of faulty region count metric in the HTTP
> server that actually showed the file count. Adding an HBCK check would
> provide an extra layer of detection to find leaks from new features or
> conservatively configured cleanup thresholds.
