-----------------------------------

             Summary: Log message about CleanerChore delegate initialization should be at INFO
                 Key: HBASE-23250
                 URL: https://issues.apache.org/jira/browse/HBASE-23250
             Project: HBase
          Issue Type: Task
          Components: master, Operability
            Reporter: Sean Busbey


Right now we log a DEBUG message as we initialize the delegates that decide on cleaner decisions:

{code}
2019-10-30 07:30:01,594 DEBUG org.apache.hadoop.hbase.master.cleaner.CleanerChore: initialize cleaner=org.apache.hadoop.hbase.replication.master.ReplicationLogCleaner
2019-10-30 07:30:01,597 DEBUG org.apache.hadoop.hbase.master.cleaner.CleanerChore: initialize cleaner=org.apache.hadoop.hbase.master.snapshot.SnapshotLogCleaner
2019-10-30 07:30:01,600 DEBUG org.apache.hadoop.hbase.master.cleaner.CleanerChore: initialize cleaner=org.apache.hadoop.hbase.master.cleaner.HFileLinkCleaner
2019-10-30 07:30:01,601 DEBUG org.apache.hadoop.hbase.master.cleaner.CleanerChore: initialize cleaner=org.apache.hadoop.hbase.master.snapshot.SnapshotHFileCleaner
2019-10-30 07:30:01,602 DEBUG org.apache.hadoop.hbase.master.cleaner.CleanerChore: initialize cleaner=org.apache.hadoop.hbase.master.cleaner.TimeToLiveHFileCleaner
{code}

Done here in CleanerChore.java:
{code}
 private void initCleanerChain(String confKey) {
    this.cleanersChain = new LinkedList<>();
    String[] logCleaners = conf.getStrings(confKey);
    if (logCleaners != null) {
      for (String className : logCleaners) {
        T logCleaner = newFileCleaner(className, conf);
        if (logCleaner != null) {
          LOG.debug("Initialize cleaner={}", className);
          this.cleanersChain.add(logCleaner);
        }
      }
    }
  }
{code}

This message should be at INFO. it doesn't happen often and knowing what plugins decide about file deletions is important all the time.
