[jira] [Created] (HBASE-12870) "Major compaction triggered" and
"Skipping major compaction" messages lack the region information
Hari Krishna Dara created HBASE-12870:
-----------------------------------------
Summary: "Major compaction triggered" and "Skipping major compaction" messages lack the region information
Key: HBASE-12870
URL: https://issues.apache.org/jira/browse/HBASE-12870
Project: HBase
Issue Type: Improvement
Components: Compaction
Affects Versions: 0.98.9
Reporter: Hari Krishna Dara
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()}}.
