The last WAL file just sits there in the RS WAL directory. If RS stops gracefully, the WAL file for meta is deleted. Otherwise if RS aborts, WAL for meta is not cleaned. It is also not split (which is correct) since master determines that the RS no longer hosts meta at the time of RS abort. > From a cluster after running ITBLL with CM, I see a lot of {{-splitting}} directories left uncleaned: > {code} > [root@os-enis-dal-test-jun-4-7 cluster-os]# sudo -u hdfs hadoop fs -ls /apps/hbase/data/WALs > Found 31 items > drwxr-xr-x - hbase hadoop 0 2015-06-05 01:14 /apps/hbase/data/WALs/hregion-58203265 > drwxr-xr-x - hbase hadoop 0 2015-06-05 07:54 /apps/hbase/data/WALs/os-enis-dal-test-jun-4-1.openstacklocal,16020,1433489308745-splitting > drwxr-xr-x - hbase hadoop 0 2015-06-05 09:28 /apps/hbase/data/WALs/os-enis-dal-test-jun-4-1.openstacklocal,16020,1433494382959-splitting > drwxr-xr-x - hbase hadoop 0 2015-06-05 10:01 /apps/hbase/data/WALs/os-enis-dal-test-jun-4-1.openstacklocal,16020,1433498252205-splitting > ... > {code} > The directories contain WALs from meta: > {code} > [root@os-enis-dal-test-jun-4-7 cluster-os]# sudo -u hdfs hadoop fs -ls /apps/hbase/data/WALs/os-enis-dal-test-jun-4-5.openstacklocal,16020,1433466904285-splitting > Found 2 items > -rw-r--r-- 3 hbase hadoop 201608 2015-06-05 03:15 /apps/hbase/data/WALs/os-enis-dal-test-jun-4-5.openstacklocal,16020,1433466904285-splitting/os-enis-dal-test-jun-4-5.openstacklocal%2C16020%2C1433466904285..meta.1433470511501.meta > -rw-r--r-- 3 hbase hadoop 44420 2015-06-05 04:36 /apps/hbase/data/WALs/os-enis-dal-test-jun-4-5.openstacklocal,16020,1433466904285-splitting/os-enis-dal-test-jun-4-5.openstacklocal%2C16020%2C1433466904285..meta.1433474111645.meta > {code} > The RS hosted the meta region for some time: > {code} > 2015-06-05 03:14:28,692 INFO [PostOpenDeployTasks:1588230740] zookeeper.MetaTableLocator: Setting hbase:meta region location in ZooKeeper as os-enis-dal-test-jun-4-5.openstacklocal,16020,1433466904285 > ... > 2015-06-05 03:15:17,302 INFO [RS_CLOSE_META-os-enis-dal-test-jun-4-5:16020-0] regionserver.HRegion: Closed hbase:meta,,1.1588230740 > {code} > In between, a WAL is created: > {code} > 2015-06-05 03:15:11,707 INFO [RS_OPEN_META-os-enis-dal-test-jun-4-5:16020-0-MetaLogRoller] wal.FSHLog: Rolled WAL /apps/hbase/data/WALs/os-enis-dal-test-jun-4-5.openstacklocal,16020,1433466904285/os-enis-dal-test-jun-4-5.openstacklocal%2C16020%2C1433466904285..meta.1433470511501.meta with entries=385, filesize=196.88 KB; new WAL /apps/hbase/data/WALs/os-enis-dal-test-jun-4-5.openstacklocal,16020,1433466904285/os-enis-dal-test-jun-4-5.openstacklocal%2C16020%2C1433466904285..meta.1433474111645.meta > {code} > When CM killed the region server later master did not see these WAL files: > {code} > ./hbase-hbase-master-os-enis-dal-test-jun-4-3.log:2015-06-05 03:36:46,075 INFO [MASTER_SERVER_OPERATIONS-os-enis-dal-test-jun-4-3:16000-0] master.SplitLogManager: started splitting 2 logs in [hdfs://os-enis-dal-test-jun-4-1.openstacklocal:8020/apps/hbase/data/WALs/os-enis-dal-test-jun-4-5.openstacklocal,16020,1433466904285-splitting] for [os-enis-dal-test-jun-4-5.openstacklocal,16020,1433466904285] > ./hbase-hbase-master-os-enis-dal-test-jun-4-3.log:2015-06-05 03:36:47,300 INFO [main-EventThread] wal.WALSplitter: Archived processed log hdfs://os-enis-dal-test-jun-4-1.openstacklocal:8020/apps/hbase/data/WALs/os-enis-dal-test-jun-4-5.openstacklocal,16020,1433466904285-splitting/os-enis-dal-test-jun-4-5.openstacklocal%2C16020%2C1433466904285.default.1433475074436 to hdfs://os-enis-dal-test-jun-4-1.openstacklocal:8020/apps/hbase/data/oldWALs/os-enis-dal-test-jun-4-5.openstacklocal%2C16020%2C1433466904285.default.1433475074436 > ./hbase-hbase-master-os-enis-dal-test-jun-4-3.log:2015-06-05 03:36:50,497 INFO [main-EventThread] wal.WALSplitter: Archived processed log hdfs://os-enis-dal-test-jun-4-1.openstacklocal:8020/apps/hbase/data/WALs/os-enis-dal-test-jun-4-5.openstacklocal,16020,1433466904285-splitting/os-enis-dal-test-jun-4-5.openstacklocal%2C16020%2C1433466904285.default.1433475175329 to hdfs://os-enis-dal-test-jun-4-1.openstacklocal:8020/apps/hbase/data/oldWALs/os-enis-dal-test-jun-4-5.openstacklocal%2C16020%2C1433466904285.default.1433475175329 > ./hbase-hbase-master-os-enis-dal-test-jun-4-3.log:2015-06-05 03:36:50,507 WARN [MASTER_SERVER_OPERATIONS-os-enis-dal-test-jun-4-3:16000-0] master.SplitLogManager: returning success without actually splitting and deleting all the log files in path hdfs://os-enis-dal-test-jun-4-1.openstacklocal:8020/apps/hbase/data/WALs/os-enis-dal-test-jun-4-5.openstacklocal,16020,1433466904285-splitting > ./hbase-hbase-master-os-enis-dal-test-jun-4-3.log:2015-06-05 03:36:50,508 INFO [MASTER_SERVER_OPERATIONS-os-enis-dal-test-jun-4-3:16000-0] master.SplitLogManager: finished splitting (more than or equal to) 129135000 bytes in 2 log files in [hdfs://os-enis-dal-test-jun-4-1.openstacklocal:8020/apps/hbase/data/WALs/os-enis-dal-test-jun-4-5.openstacklocal,16020,1433466904285-splitting] in 4433ms > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
