I have Installed Apache Hadoop Pseudo Distributed Mode on a Single Node with hadoop-1.0.4.It <http://hadoop-1.0.4.it/> works fine and i tried some examples of wordcount on putty too. But getting into eclipse IDE on windows i was struck up with the first program. I have already installed jdk6 and mapreduce plugin version1.0.4 also. When trying to run on hadoop error occurs as follows:- * WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable * ERROR security.UserGroupInformation: PriviledgedActionException as:ramyas cause:java.io.IOException: Failed to set permissions of path: \tmp\hadoop-ramyas\mapred\staging\ramyas-1375395355\.staging to 0700 * java.io.IOException : Failed to set permissions of path: \tmp\hadoop-ramyas\mapred\staging\ramyas-1375395355\.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:856) * at org.apache.hadoop.mapred.JobClient$2.run( JobClient.java:850) * at java.security.AccessController.doPrivileged( Native Method) * at javax.security.auth.Subject.doAs(Unknown Source) * at org.apache.hadoop.security.UserGroupInformation.doAs( UserGroupInformation.java:1121) * at org.apache.hadoop.mapred.JobClient.submitJobInternal( JobClient.java:850) * at org.apache.hadoop.mapred.JobClient.submitJob( JobClient.java:824) * at org.apache.hadoop.mapred.JobClient.runJob( JobClient.java:1261) * at WordCount.main( WordCount.java:29) * Also I want to know about configuring map/reduce plugin in eclipse.
