I use Hadoop distribution 1.1.2. When I try to run example wordcount routine I get following error.
Input command:
'D:/Files/hadoop-1.1.2/hadoop-1.1.2/bin/hadoop' jar 'D:/Files/hadoop-1.1.2/hadoop-1.1.2/hadoop-examples-1.1.2.jar' wordcount input output
The result:
13/07/03 11:02:42 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 13/07/03 11:02:42 ERROR security.UserGroupInformation: PriviledgedActionException as:PC cause:java.io.IOException: Failed to set permissions of path: \tmp\hadoop-PC\mapred\staging\PC119237705.staging to 0700 java.io.IOException: Failed to set permissions of path: \tmp\hadoop-PC\mapred\staging\PC119237705.staging to 0700 at org.apache.hadoop.fs.FileUtil.checkReturnValue(FileUtil.java:689) at org.apache.hadoop.fs.FileUtil.setPermission(FileUtil.java:662) at org.apache.hadoop.fs.RawLocalFileSystem.setPermission(RawLocalFileSystem.java:509) at org.apache.hadoop.fs.RawLocalFileSystem.mkdirs(RawLocalFileSystem.java:344) at org.apache.hadoop.fs.FilterFileSystem.mkdirs(FilterFileSystem.java:189) at org.apache.hadoop.mapreduce.JobSubmissionFiles.getStagingDir(JobSubmissionFiles.java:116) at org.apache.hadoop.mapred.JobClient$2.run(JobClient.java:918) at org.apache.hadoop.mapred.JobClient$2.run(JobClient.java:912) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:415) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1149) at org.apache.hadoop.mapred.JobClient.submitJobInternal(JobClient.java:912) at org.apache.hadoop.mapreduce.Job.submit(Job.java:500) at org.apache.hadoop.mapreduce.Job.waitForCompletion(Job.java:530) at org.apache.hadoop.examples.WordCount.main(WordCount.java:67) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.hadoop.util.ProgramDriver$ProgramDescription.invoke(ProgramDriver.java:68) at org.apache.hadoop.util.ProgramDriver.driver(ProgramDriver.java:139) at org.apache.hadoop.examples.ExampleDriver.main(ExampleDriver.java:64) 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.util.RunJar.main(RunJar.java:156)
