Hi, Hadoop/HDFS newbie. Been struggling with getting the streaming example working with -archives. c.f. http://hadoop.apache.org/common/docs/r0.20.1/streaming.html#Large+files+and+archives+in+Hadoop+Streaming
My environment is the Pseudo-distributed environment setup per: http://hadoop.apache.org/common/docs/current/quickstart.html#PseudoDistributed I've run into a couple issues. First issue is "FileNotFoundException" when the #symlink suffix is specified with the -archives or -files options as per the tutorial. hadoop jar $HADOOP_HOME/hadoop-0.20.1-streaming.jar -archives "hdfs://localhost:9000/user/me/samples/cachefile/cachedir.jar#testlink" -input "samples/cachefile/input.txt" -mapper "xargs cat" -reducer "cat" -output "samples/cachefile/out" java.io.FileNotFoundException: File hdfs://localhost:9000/user/me/samples/cachefile/cachedir.jar#testlink does not exist. at org.apache.hadoop.util.GenericOptionsParser.validateFiles(GenericOptionsParser.java:349) at org.apache.hadoop.util.GenericOptionsParser.processGeneralOptions(GenericOptionsParser.java:275) at org.apache.hadoop.util.GenericOptionsParser.parseGeneralOptions(GenericOptionsParser.java:375) at org.apache.hadoop.util.GenericOptionsParser.<init>(GenericOptionsParser.java:153) at org.apache.hadoop.util.GenericOptionsParser.<init>(GenericOptionsParser.java:138) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:59) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:79) at org.apache.hadoop.streaming.HadoopStreaming.main(HadoopStreaming.java:32) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.util.RunJar.main(RunJar.java:156) If I remove the "#testlink" from the archives definition, the error goes away but the symlink is not created, as per the tutorial documentation. I've seen this JIRA issue http://issues.apache.org/jira/browse/HADOOP-6178, shows no FIX version, but the Issue Links to others which are supposedly fixed in 0.20.1 which I have. 2nd issue is "Unrecognized option -archives" when -archives is specified at the end of the arg list. hadoop jar $HADOOP_HOME/hadoop/hadoop-0.20.1-streaming.jar -input "samples/cachefile/input.txt" -mapper "xargs cat" -reducer "cat" -output "samples/cachefile/out9" -archives "hdfs://localhost:9000/user/me/samples/cachefile/cachedir.jar#testlink" 10/02/19 14:29:11 ERROR streaming.StreamJob: Unrecognized option: -archives Any help getting past this appreciated. Am I missing a configuration setting that allows symlinking? Really hoping to use the archives feature. -Michael
