一、問題描述
日志文件信息如下：
2019-07-18 11:20:28,104 INFO nodemanager.NodeManager (LogAdapter.java:info(45)) - registered UNIX signal handlers for [TERM, HUP, INT] 2019-07-18 11:20:29,069 INFO recovery.NMLeveldbStateStoreService (NMLeveldbStateStoreService.java:openDatabase(963)) - Using state database at /var/log/hadoop-yarn/nodemanager/recovery-state/yarn-nm-state for recovery 2019-07-18 11:20:29,103 INFO service.AbstractService (AbstractService.java:noteFailure(272)) - Service org.apache.hadoop.yarn.server.nodemanager.recovery.NMLeveldbStateStoreService failed in state INITED; cause: org.fusesource.leveldbjni.internal.NativeDB$DBException: IO error: /var/log/hadoop-yarn/nodemanager/recovery-state/yarn-nm-state/MANIFEST-000002: No such file or directory org.fusesource.leveldbjni.internal.NativeDB$DBException: IO error: /var/log/hadoop-yarn/nodemanager/recovery-state/yarn-nm-state/MANIFEST-000002: No such file or directory at org.fusesource.leveldbjni.internal.NativeDB.checkStatus(NativeDB.java:200) at org.fusesource.leveldbjni.internal.NativeDB.open(NativeDB.java:218) at org.fusesource.leveldbjni.JniDBFactory.open(JniDBFactory.java:168) at org.apache.hadoop.yarn.server.nodemanager.recovery.NMLeveldbStateStoreService.openDatabase(NMLeveldbStateStoreService.java:966) at org.apache.hadoop.yarn.server.nodemanager.recovery.NMLeveldbStateStoreService.initStorage(NMLeveldbStateStoreService.java:953) at org.apache.hadoop.yarn.server.nodemanager.recovery.NMStateStoreService.serviceInit(NMStateStoreService.java:200) at org.apache.hadoop.service.AbstractService.init(AbstractService.java:163) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.initAndStartRecoveryStore(NodeManager.java:178) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.serviceInit(NodeManager.java:220) at org.apache.hadoop.service.AbstractService.init(AbstractService.java:163) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.initAndStartNodeManager(NodeManager.java:546) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.main(NodeManager.java:594) 2019-07-18 11:20:29,106 INFO service.AbstractService (AbstractService.java:noteFailure(272)) - Service NodeManager failed in state INITED; cause: org.apache.hadoop.service.ServiceStateException: org.fusesource.leveldbjni.internal.NativeDB$DBException: IO error: /var/log/hadoop-yarn/nodemanager/recovery-state/yarn-nm-state/MANIFEST-000002: No such file or directory org.apache.hadoop.service.ServiceStateException: org.fusesource.leveldbjni.internal.NativeDB$DBException: IO error: /var/log/hadoop-yarn/nodemanager/recovery-state/yarn-nm-state/MANIFEST-000002: No such file or directory at org.apache.hadoop.service.ServiceStateException.convert(ServiceStateException.java:59) at org.apache.hadoop.service.AbstractService.init(AbstractService.java:172) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.initAndStartRecoveryStore(NodeManager.java:178) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.serviceInit(NodeManager.java:220) at org.apache.hadoop.service.AbstractService.init(AbstractService.java:163) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.initAndStartNodeManager(NodeManager.java:546) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.main(NodeManager.java:594) .......
二、解決辦法一
i. 刪除 yarn-nm-state 目錄的所有文件再次啟動
[root@zwlbs3 ~]# cd /var/log/hadoop-yarn/nodemanager/recovery-state/yarn-nm-state/ [root@zwlbs3 yarn-nm-state]# ls 000003.log CURRENT LOCK MANIFEST-000002 [root@zwlbs3 yarn-nm-state]# rm -rf *
ii. 再次啟動 NodeManager 組件
我這里使用的是 Ambari 來管理的，直接就Web界面操作，也可以使用命令操作啟動。
iii. 查看是否啟動成功，已啟動成功
[root@zwlbs3 ~]# jps 4832 DataNode 11425 Jps 7091 HRegionServer 3894 NodeManager
三、解決辦法二（如果辦法一無效，試試辦法二）
i. 如果過一會變成 stop 狀態，報錯日志跟上面相同，如下：
2019-08-07 17:14:01,850 INFO nodemanager.NodeManager (LogAdapter.java:info(45)) - registered UNIX signal handlers for [TERM, HUP, INT] 2019-08-07 17:14:02,859 INFO recovery.NMLeveldbStateStoreService (NMLeveldbStateStoreService.java:openDatabase(963)) - Using state database at /var/log/hadoop-yarn/nodema nager/recovery-state/yarn-nm-state for recovery 2019-08-07 17:14:02,891 INFO service.AbstractService (AbstractService.java:noteFailure(272)) - Service org.apache.hadoop.yarn.server.nodemanager.recovery.NMLeveldbStateSt oreService failed in state INITED; cause: org.fusesource.leveldbjni.internal.NativeDB$DBException: IO error: /var/log/hadoop-yarn/nodemanager/recovery-state/yarn-nm-state/ MANIFEST-000002: No such file or directory org.fusesource.leveldbjni.internal.NativeDB$DBException: IO error: /var/log/hadoop-yarn/nodemanager/recovery-state/yarn-nm-state/MANIFEST-000002: No such file or directory at org.fusesource.leveldbjni.internal.NativeDB.checkStatus(NativeDB.java:200) at org.fusesource.leveldbjni.internal.NativeDB.open(NativeDB.java:218) at org.fusesource.leveldbjni.JniDBFactory.open(JniDBFactory.java:168) at org.apache.hadoop.yarn.server.nodemanager.recovery.NMLeveldbStateStoreService.openDatabase(NMLeveldbStateStoreService.java:966) at org.apache.hadoop.yarn.server.nodemanager.recovery.NMLeveldbStateStoreService.initStorage(NMLeveldbStateStoreService.java:953) at org.apache.hadoop.yarn.server.nodemanager.recovery.NMStateStoreService.serviceInit(NMStateStoreService.java:200) at org.apache.hadoop.service.AbstractService.init(AbstractService.java:163) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.initAndStartRecoveryStore(NodeManager.java:178) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.serviceInit(NodeManager.java:220) at org.apache.hadoop.service.AbstractService.init(AbstractService.java:163) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.initAndStartNodeManager(NodeManager.java:546) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.main(NodeManager.java:594) 2019-08-07 17:14:02,895 INFO service.AbstractService (AbstractService.java:noteFailure(272)) - Service NodeManager failed in state INITED; cause: org.apache.hadoop.servic e.ServiceStateException: org.fusesource.leveldbjni.internal.NativeDB$DBException: IO error: /var/log/hadoop-yarn/nodemanager/recovery-state/yarn-nm-state/MANIFEST-000002: No such file or directory org.apache.hadoop.service.ServiceStateException: org.fusesource.leveldbjni.internal.NativeDB$DBException: IO error: /var/log/hadoop-yarn/nodemanager/recovery-state/yarn-nm -state/MANIFEST-000002: No such file or directory .......
ii. 刪除 yarn-nm-state 目錄的所有文件
[root@zwlbs3 ~]# cd /var/log/hadoop-yarn/nodemanager/recovery-state/yarn-nm-state/ [root@zwlbs3 yarn-nm-state]# ls 000003.log CURRENT LOCK MANIFEST-000002 [root@zwlbs3 yarn-nm-state]# rm -rf *
iii. 重啟該服務器的整個Hadoop
命令行操作請自行到 Hadoop 目錄下重啟所有組件即可。
