> 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
> {noformat}
> {noformat}
> 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()}}.
