Jeff Zhang created YARN-2184: -------------------------------- Summary: ResourceManager may fail due to name node in safe mode Key: YARN-2184 URL: https://issues.apache.org/jira/browse/YARN-2184 Project: Hadoop YARN Issue Type: Improvement Components: resourcemanager Affects Versions: 2.4.0 Reporter: Jeff Zhang Assignee: Jeff Zhang
If the historyservice is enabled in resourcemanager, it will try to mkdir when service is inited. And at that time maybe the name node is still in safemode which may cause the historyservice failed and then cause the resouremanager fail. It would be very possible when the cluster is restarted when namenode will be in safemode in a long time. Here's the error logs: {code} Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hdfs.server.namenode.SafeModeException): Cannot create directory /Users/jzhang/Java/lib/hadoop-2.4.0/logs/yarn/system/history/ApplicationHistoryDataRoot. Name node is in safe mode. The reported blocks 85 has reached the threshold 0.9990 of total blocks 85. The number of live datanodes 1 has reached the minimum number 0. In safe mode extension. Safe mode will be turned off automatically in 19 seconds. at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.checkNameNodeSafeMode(FSNamesystem.java:1195) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.mkdirsInt(FSNamesystem.java:3564) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.mkdirs(FSNamesystem.java:3540) at org.apache.hadoop.hdfs.server.namenode.NameNodeRpcServer.mkdirs(NameNodeRpcServer.java:754) at org.apache.hadoop.hdfs.protocolPB.ClientNamenodeProtocolServerSideTranslatorPB.mkdirs(ClientNamenodeProtocolServerSideTranslatorPB.java:558) at org.apache.hadoop.hdfs.protocol.proto.ClientNamenodeProtocolProtos$ClientNamenodeProtocol$2.callBlockingMethod(ClientNamenodeProtocolProtos.java) at org.apache.hadoop.ipc.ProtobufRpcEngine$Server$ProtoBufRpcInvoker.call(ProtobufRpcEngine.java:585) at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:928) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:2013) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:2009) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:415) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1548) at org.apache.hadoop.ipc.Server$Handler.run(Server.java:2007) at org.apache.hadoop.ipc.Client.call(Client.java:1410) at org.apache.hadoop.ipc.Client.call(Client.java:1363) at org.apache.hadoop.ipc.ProtobufRpcEngine$Invoker.invoke(ProtobufRpcEngine.java:206) at com.sun.proxy.$Proxy14.mkdirs(Unknown Source) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.hadoop.io.retry.RetryInvocationHandler.invokeMethod(RetryInvocationHandler.java:190) at org.apache.hadoop.io.retry.RetryInvocationHandler.invoke(RetryInvocationHandler.java:103) at com.sun.proxy.$Proxy14.mkdirs(Unknown Source) at org.apache.hadoop.hdfs.protocolPB.ClientNamenodeProtocolTranslatorPB.mkdirs(ClientNamenodeProtocolTranslatorPB.java:500) at org.apache.hadoop.hdfs.DFSClient.primitiveMkdir(DFSClient.java:2553) at org.apache.hadoop.hdfs.DFSClient.mkdirs(DFSClient.java:2524) at org.apache.hadoop.hdfs.DistributedFileSystem$16.doCall(DistributedFileSystem.java:827) at org.apache.hadoop.hdfs.DistributedFileSystem$16.doCall(DistributedFileSystem.java:823) at org.apache.hadoop.fs.FileSystemLinkResolver.resolve(FileSystemLinkResolver.java:81) at org.apache.hadoop.hdfs.DistributedFileSystem.mkdirsInternal(DistributedFileSystem.java:823) at org.apache.hadoop.hdfs.DistributedFileSystem.mkdirs(DistributedFileSystem.java:816) at org.apache.hadoop.fs.FileSystem.mkdirs(FileSystem.java:1815) at org.apache.hadoop.yarn.server.applicationhistoryservice.FileSystemApplicationHistoryStore.serviceInit(FileSystemApplicationHistoryStore.java:120) at org.apache.hadoop.service.AbstractService.init(AbstractService.java:163) ... 10 more 2014-06-20 11:06:25,220 INFO org.apache.hadoop.yarn.server.resourcemanager.ResourceManager: SHUTDOWN_MSG: /************************************************************ SHUTDOWN_MSG: Shutting down ResourceManager at jzhangMBPr.local/192.168.100.152 {code} -- This message was sent by Atlassian JIRA (v6.2#6252)
