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)
I have problem to locate the particular cause of this error. Please help.
Looks like you have hit this. You might find this patch helpful. But, before that you might wanna try changing the directory permissions to 755 and re-running the job.
