> The below messages coming from {{RatioBasedCompactionPolicy}} log the default
> {{.toString()}} output of itself, which is not useful:
> {noformat}

> org.apache.hadoop.hbase.regionserver.compactions.RatioBasedCompactionPolicy:

> org.apache.hadoop.hbase.regionserver.compactions.RatioBasedCompactionPolicy:
> Skipping major compaction of

> because one (major) compacted file only and oldestTime 6795587394ms is <

> It should log the store/region information instead. Unfortunately, this
> information seems to be unavailable at this point, so more context needs to
> be supplied while calling {{RatioBasedCompactionPolicy.isMajorCompaction()}}.
