I read that I can use it with python(using jython)... I tried the example but jython cannot find the module org.apache.hadoop.fs...(I dont know much about java). Anyone knows where can I find that module and where should I place it?? Also, I tried the java example and I get too many errors.... I used the command bin/hadoop jar hadoop-*-examples.jar wordcount mydfs/LICENSE.txt mydfs/a but I get the following errors: java.lang.RuntimeException: java.net.SocketTimeoutException: timed out waiting for rpc response at org.apache.hadoop.mapred.JobConf.getWorkingDirectory(JobConf.java:247) at org.apache.hadoop.mapred.JobConf.setInputPath(JobConf.java:150) at org.apache.hadoop.examples.WordCount.main(WordCount.java:137) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.apache.hadoop.util.ProgramDriver$ProgramDescription.invoke(ProgramDriver .java:71) at org.apache.hadoop.util.ProgramDriver.driver(ProgramDriver.java:143) at org.apache.hadoop.examples.ExampleDriver.main(ExampleDriver.java:40) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.apache.hadoop.util.RunJar.main(RunJar.java:155) Caused by: java.net.SocketTimeoutException: timed out waiting for rpc response at org.apache.hadoop.ipc.Client.call(Client.java:469) at org.apache.hadoop.ipc.RPC$Invoker.invoke(RPC.java:164) at org.apache.hadoop.dfs.$Proxy0.getProtocolVersion(Unknown Source) at org.apache.hadoop.ipc.RPC.getProxy(RPC.java:248) at org.apache.hadoop.dfs.DFSClient.<init>(DFSClient.java:106) at org.apache.hadoop.dfs.DistributedFileSystem.initialize(DistributedFileSystem .java:65) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:160) at org.apache.hadoop.fs.FileSystem.getNamed(FileSystem.java:119) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:91) at org.apache.hadoop.mapred.JobConf.getWorkingDirectory(JobConf.java:243) Anyone can help me???
