hadoop中的一个问题

在使用hadoop fs -put src dest这条命令从linux上传文件到hadoop老是不成功，网上的方法试了好久都没有成功，最后发现是磁盘空间不足造成的!

查看hadoop日志信息，在hadoop根目录的logs文件夹中hadoop-root-namenode-hadoop.log中有如下错误信息：2014-05-29 19:45:08,359 WARN org.apache.hadoop.mapred.JobTracker: FileSystem is not ready yet! 2014-05-29 19:45:08,367 WARN org.apache.hadoop.mapred.JobTracker: Failed to initialize recovery manager. org.apache.hadoop.ipc.RemoteException: java.io.IOException: File /usr/local/hadoop/mapred/system/jobtracker.info could only be replicated to 0 nodes, instead of 1 at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.getAdditionalBlock(FSNamesystem.java:1639) at org.apache.hadoop.hdfs.server.namenode.NameNode.addBlock(NameNode.java:736) at sun.reflect.GeneratedMethodAccessor6.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:578) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:1393) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:1389) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:396) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1149) at org.apache.hadoop.ipc.Server$Handler.run(Server.java:1387) at org.apache.hadoop.ipc.Client.call(Client.java:1107) at org.apache.hadoop.ipc.RPC$Invoker.invoke(RPC.java:229) at $Proxy7.addBlock(Unknown Source) at sun.reflect.GeneratedMethodAccessor7.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.io.retry.RetryInvocationHandler.invokeMethod(RetryInvocationHandler.java:85) at org.apache.hadoop.io.retry.RetryInvocationHandler.invoke(RetryInvocationHandler.java:62) at $Proxy7.addBlock(Unknown Source) at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.locateFollowingBlock(DFSClient.java:3686) at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.nextBlockOutputStream(DFSClient.java:3546) at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.access$2600(DFSClient.java:2749) at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream$DataStreamer.run(DFSClient.java:2989) 2014-05-29 19:45:09,369 WARN org.apache.hadoop.mapred.JobTracker: Retrying... 2014-05-29 19:45:09,406 WARN org.apache.hadoop.hdfs.DFSClient: DataStreamer Exception: org.apache.hadoop.ipc.RemoteException: java.io.IOException: File /usr/local/hadoop/mapred/system/jobtracker.info could only be replicated to 0 nodes, instead of 1 at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.getAdditionalBlock(FSNamesystem.java:1639) at org.apache.hadoop.hdfs.server.namenode.NameNode.addBlock(NameNode.java:736) at sun.reflect.GeneratedMethodAccessor6.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:578) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:1393) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:1389) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:396) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1149) at org.apache.hadoop.ipc.Server$Handler.run(Server.java:1387) at org.apache.hadoop.ipc.Client.call(Client.java:1107) at org.apache.hadoop.ipc.RPC$Invoker.invoke(RPC.java:229) at $Proxy7.addBlock(Unknown Source) at sun.reflect.GeneratedMethodAccessor7.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.io.retry.RetryInvocationHandler.invokeMethod(RetryInvocationHandler.java:85) at org.apache.hadoop.io.retry.RetryInvocationHandler.invoke(RetryInvocationHandler.java:62) at $Proxy7.addBlock(Unknown Source) at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.locateFollowingBlock(DFSClient.java:3686) at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.nextBlockOutputStream(DFSClient.java:3546) at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.access$2600(DFSClient.java:2749) at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream$DataStreamer.run(DFSClient.java:2989) 2014-05-29 19:45:09,406 WARN org.apache.hadoop.hdfs.DFSClient: Error Recovery for block null bad datanode[0] nodes == null 2014-05-29 19:45:09,406 WARN org.apache.hadoop.hdfs.DFSClient: Could not get block locations.
