i have this error message i don't know if the problem is of the network because the ip adress of master is different of what is shown in the third line 11/02/24 10:43:47 INFO namenode.NameNode: STARTUP_MSG: /************************************************************ STARTUP_MSG: Starting NameNode STARTUP_MSG: host = ubuntu/127.0.1.1 STARTUP_MSG: args = [] STARTUP_MSG: version = 0.20.2 STARTUP_MSG: build = https://svn.apache.org/repos/asf/hadoop/common/branches/branch-0.20 -r 911707; compiled by 'chrisdo' on Fri Feb 19 08:07:34 UTC 2010 ************************************************************/ 11/02/24 10:43:48 INFO metrics.RpcMetrics: Initializing RPC Metrics with hostName=NameNode, port=8020 11/02/24 10:43:48 INFO namenode.NameNode: Namenode up at: ubuntu.local/157.159.103.83:8020 11/02/24 10:43:48 INFO jvm.JvmMetrics: Initializing JVM Metrics with processName=NameNode, sessionId=null 11/02/24 10:43:48 INFO metrics.NameNodeMetrics: Initializing NameNodeMeterics using context object:org.apache.hadoop.metrics.spi.NullContext 11/02/24 10:43:48 INFO namenode.FSNamesystem: fsOwner=vadmin,vadmin,adm,dialout,cdrom,plugdev,lpadmin,sambashare,admin 11/02/24 10:43:48 INFO namenode.FSNamesystem: supergroup=supergroup 11/02/24 10:43:48 INFO namenode.FSNamesystem: isPermissionEnabled=true 11/02/24 10:43:48 INFO metrics.FSNamesystemMetrics: Initializing FSNamesystemMetrics using context object:org.apache.hadoop.metrics.spi.NullContext 11/02/24 10:43:48 INFO namenode.FSNamesystem: Registered FSNamesystemStatusMBean 11/02/24 10:43:48 INFO common.Storage: Storage directory /usr/local/hadoop-0.20.2/namespace does not exist. 11/02/24 10:43:48 ERROR namenode.FSNamesystem: FSNamesystem initialization failed. org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory /usr/local/hadoop-0.20.2/namespace is in an inconsistent state: storage directory does not exist or is not accessible. at org.apache.hadoop.hdfs.server.namenode.FSImage.recoverTransitionRead(FSImage.java:290) at org.apache.hadoop.hdfs.server.namenode.FSDirectory.loadFSImage(FSDirectory.java:87) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.initialize(FSNamesystem.java:311) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.<init>(FSNamesystem.java:292) at org.apache.hadoop.hdfs.server.namenode.NameNode.initialize(NameNode.java:201) at org.apache.hadoop.hdfs.server.namenode.NameNode.<init>(NameNode.java:279) at org.apache.hadoop.hdfs.server.namenode.NameNode.createNameNode(NameNode.java:956) at org.apache.hadoop.hdfs.server.namenode.NameNode.main(NameNode.java:965) 11/02/24 10:43:48 INFO ipc.Server: Stopping server on 8020 11/02/24 10:43:48 ERROR namenode.NameNode: org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory /usr/local/hadoop-0.20.2/namespace is in an inconsistent state: storage directory does not exist or is not accessible. at org.apache.hadoop.hdfs.server.namenode.FSImage.recoverTransitionRead(FSImage.java:290) at org.apache.hadoop.hdfs.server.namenode.FSDirectory.loadFSImage(FSDirectory.java:87) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.initialize(FSNamesystem.java:311) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.<init>(FSNamesystem.java:292) at org.apache.hadoop.hdfs.server.namenode.NameNode.initialize(NameNode.java:201) at org.apache.hadoop.hdfs.server.namenode.NameNode.<init>(NameNode.java:279) at org.apache.hadoop.hdfs.server.namenode.NameNode.createNameNode(NameNode.java:956) at org.apache.hadoop.hdfs.server.namenode.NameNode.main(NameNode.java:965) 11/02/24 10:43:48 INFO namenode.NameNode: SHUTDOWN_MSG: /************************************************************ SHUTDOWN_MSG: Shutting down NameNode at ubuntu/127.0.1.1 ************************************************************/ thanks for your help best regards khaled
