Hi, Following is a description of what I am trying to do and the steps I followed.
GOAL: a). Install Hadoop 1.0.3 b). Hadoop in a standalone (or local) mode c). OS: Windows 7 STEPS FOLLOWED: 1. 1. I followed instructions from: http://www.oreillynet.com/pub/a/other-programming/excerpts/hadoop-tdg/installing-apache-hadoop.html. Listing the steps I did - a. I went to: http://hadoop.apache.org/core/releases.html. b. I installed hadoop-1.0.3 by downloading “hadoop-1.0.3.tar.gz” and unzipping/untarring the file. c. I installed JDK 1.6 and set up JAVA_HOME to point to it. d. I set up HADOOP_INSTALL to point to my Hadoop install location. I updated my PATH variable to have $HADOOP_INSTALL/bin e. After the above steps, I ran the command: “hadoop version” and got the following information: $ hadoop version Hadoop 1.0.3 Subversion https://svn.apache.org/repos/asf/hadoop/common/branches/branch-1.0 -r 1335192 Compiled by hortonfo on Tue May 8 20:31:25 UTC 2012 From source with checksum e6b0c1e23dcf76907c5fecb4b832f3be 2. 2. The standalone was very easy to install as described above. Then, I tried to run a sample command as given in: http://hadoop.apache.org/common/docs/r0.17.2/quickstart.html#Local Specifically, the steps followed were: a. cd $HADOOP_INSTALL b. mkdir input c. cp conf/*.xml input d. bin/hadoop jar hadoop-examples-1.0.3.jar grep input output ‘dfs[a-z.]+’ and got the following error: $ bin/hadoop jar hadoop-examples-1.0.3.jar grep input output 'dfs[a-z.]+' 12/09/03 15:41:57 WARN util.NativeCodeLoader: Unable to load native-hadoop libra ry for your platform... using builtin-java classes where applicable 12/09/03 15:41:57 ERROR security.UserGroupInformation: PriviledgedActionExceptio n as:upendyal cause:java.io.IOException: Failed to set permissions of path: \tmp \hadoop-upendyal\mapred\staging\upendyal-1075683580\.staging to 0700 java.io.IOException: Failed to set permissions of path: \tmp\hadoop-upendyal\map red\staging\upendyal-1075683580\.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(RawLocalFileSys tem.java:509) at org.apache.hadoop.fs.RawLocalFileSystem.mkdirs(RawLocalFileSystem.jav a:344) at org.apache.hadoop.fs.FilterFileSystem.mkdirs(FilterFileSystem.java:18 9) at org.apache.hadoop.mapreduce.JobSubmissionFiles.getStagingDir(JobSubmi ssionFiles.java:116) at org.apache.hadoop.mapred.JobClient$2.run(JobClient.java:856) at org.apache.hadoop.mapred.JobClient$2.run(JobClient.java:850) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Unknown Source) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInforma tion.java:1121) at org.apache.hadoop.mapred.JobClient.submitJobInternal(JobClient.java:8 50) at org.apache.hadoop.mapred.JobClient.submitJob(JobClient.java:824) at org.apache.hadoop.mapred.JobClient.runJob(JobClient.java:1261) at org.apache.hadoop.examples.Grep.run(Grep.java:69) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65) at org.apache.hadoop.examples.Grep.main(Grep.java:93) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.apache.hadoop.util.ProgramDriver$ProgramDescription.invoke(Progra mDriver.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(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:156) 3. 3. I googled the problem and found the following links but none of these suggestions helped. Most people seem to be getting a resolution when they change the version of Hadoop. a. http://mail-archives.apache.org/mod_mbox/hadoop-common-user/201105.mbox/%[email protected]%3E b. http://comments.gmane.org/gmane.comp.jakarta.lucene.hadoop.user/25837 Is this a problem in the version of Hadoop I selected OR am I doing something wrong? I would appreciate any help with this. Thanks Udayini
