adoroszlai opened a new pull request #502: HDDS-2955. Unnecessary log messages in DBStoreBuilder URL: https://github.com/apache/hadoop-ozone/pull/502 ## What changes were proposed in this pull request? 1. Reduce log level of "using default/custom profile ..." messages to `debug`. 2. Avoid logging both "default" and "custom" for the same table by refactoring the code. 3. Add constant for `String` version of `DEFAULT_COLUMN_FAMILY`. https://issues.apache.org/jira/browse/HDDS-2955 ## How was this patch tested? Verified log in compose cluster. with default info level: ``` recon_1 | 2020-01-29 17:14:39,085 [pool-8-thread-1] INFO impl.OzoneManagerServiceProviderImpl: Got new checkpoint from OM : /data/metadata/recon/om.snapshot.db_1580318078998 recon_1 | 2020-01-29 17:14:39,085 [pool-8-thread-1] INFO recovery.ReconOmMetadataManagerImpl: Cleaning up old OM snapshot db at /data/metadata/recon/om.snapshot.db_1580317479076. recon_1 | 2020-01-29 17:14:39,231 [pool-8-thread-1] INFO recovery.ReconOmMetadataManagerImpl: Created OM DB handle from snapshot at /data/metadata/recon/om.snapshot.db_1580318078998. ``` and with debug level: ``` recon_1 | 2020-01-29 17:00:12,434 [pool-8-thread-1] INFO impl.OzoneManagerServiceProviderImpl: Got new checkpoint from OM : /data/metadata/recon/om.snapshot.db_1580317212331 recon_1 | 2020-01-29 17:00:12,434 [pool-8-thread-1] INFO recovery.ReconOmMetadataManagerImpl: Cleaning up old OM snapshot db at /data/metadata/recon/om.snapshot.db_1580316612245. recon_1 | 2020-01-29 17:00:12,438 [pool-8-thread-1] DEBUG db.DBStoreBuilder: default profile:DBProfile.DISK recon_1 | 2020-01-29 17:00:12,438 [pool-8-thread-1] DEBUG db.DBStoreBuilder: using default profile for table:userTable recon_1 | 2020-01-29 17:00:12,442 [pool-8-thread-1] DEBUG db.DBStoreBuilder: using default profile for table:volumeTable recon_1 | 2020-01-29 17:00:12,442 [pool-8-thread-1] DEBUG db.DBStoreBuilder: using default profile for table:bucketTable recon_1 | 2020-01-29 17:00:12,443 [pool-8-thread-1] DEBUG db.DBStoreBuilder: using default profile for table:keyTable recon_1 | 2020-01-29 17:00:12,443 [pool-8-thread-1] DEBUG db.DBStoreBuilder: using default profile for table:deletedTable recon_1 | 2020-01-29 17:00:12,443 [pool-8-thread-1] DEBUG db.DBStoreBuilder: using default profile for table:openKeyTable recon_1 | 2020-01-29 17:00:12,444 [pool-8-thread-1] DEBUG db.DBStoreBuilder: using default profile for table:s3Table recon_1 | 2020-01-29 17:00:12,444 [pool-8-thread-1] DEBUG db.DBStoreBuilder: using default profile for table:multipartInfoTable recon_1 | 2020-01-29 17:00:12,444 [pool-8-thread-1] DEBUG db.DBStoreBuilder: using default profile for table:dTokenTable recon_1 | 2020-01-29 17:00:12,445 [pool-8-thread-1] DEBUG db.DBStoreBuilder: using default profile for table:s3SecretTable recon_1 | 2020-01-29 17:00:12,445 [pool-8-thread-1] DEBUG db.DBStoreBuilder: using default profile for table:prefixTable recon_1 | 2020-01-29 17:00:12,447 [pool-8-thread-1] DEBUG db.DBStoreBuilder: using default profile for table:default recon_1 | 2020-01-29 17:00:12,451 [pool-8-thread-1] DEBUG db.DBStoreBuilder: Using default options: DBProfile.DISK recon_1 | 2020-01-29 17:00:12,561 [pool-8-thread-1] INFO recovery.ReconOmMetadataManagerImpl: Created OM DB handle from snapshot at /data/metadata/recon/om.snapshot.db_1580317212331. ``` https://github.com/adoroszlai/hadoop-ozone/runs/415576820
