> The below messages coming from {{RatioBasedCompactionPolicy}} log the default {{.toString()}} output of itself, which is not useful:
> {noformat}
> 2015-01-16 06:15:07,166 DEBUG org.apache.hadoop.hbase.regionserver.compactions.RatioBasedCompactionPolicy: Major compaction triggered on store org.apache.hadoop.hbase.regionserver.compactions.ExploringCompactionPolicy@4acab1f5; time since last major compaction 339994249ms

> 2015-01-16 09:49:12,872 DEBUG org.apache.hadoop.hbase.regionserver.compactions.RatioBasedCompactionPolicy: Skipping major compaction of org.apache.hadoop.hbase.regionserver.compactions.ExploringCompactionPolicy@7b9f47bb because one (major) compacted file only and oldestTime 6795587394ms is < ttl=15552000000
> {noformat}
> 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()}}.
