Hi everyone, I'm trying to run C++ code in Hadoop, following the explanation posted in: http://cs.smith.edu/dftwiki/index.php/Hadoop_Tutorial_2.2_--_Running_C%2B%2B_Programs_on_Hadoop
But I'm facing the following problem when running the compiled code: java.lang.Exception: java.lang.NullPointerException at org.apache.hadoop.mapred.LocalJobRunner$Job.runTasks(LocalJobRunner.java:462) at org.apache.hadoop.mapred.LocalJobRunner$Job.run(LocalJobRunner.java:522) Caused by: java.lang.NullPointerException at org.apache.hadoop.mapred.pipes.Application.<init>(Application.java:104) at org.apache.hadoop.mapred.pipes.PipesMapRunner.run(PipesMapRunner.java:69) at org.apache.hadoop.mapred.MapTask.runOldMapper(MapTask.java:450) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:343) at org.apache.hadoop.mapred.LocalJobRunner$Job$MapTaskRunnable.run(LocalJobRunner.java:243) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) 14/12/10 15:10:42 INFO mapreduce.Job: Job job_local313628026_0001 running in uber mode : false 14/12/10 15:10:42 INFO mapreduce.Job: map 0% reduce 0% 14/12/10 15:10:42 INFO mapreduce.Job: Job job_local313628026_0001 failed with state FAILED due to: NA 14/12/10 15:10:42 INFO mapreduce.Job: Counters: 0 Exception in thread "main" java.io.IOException: Job failed! at org.apache.hadoop.mapred.JobClient.runJob(JobClient.java:836) at org.apache.hadoop.mapred.pipes.Submitter.runJob(Submitter.java:264) at org.apache.hadoop.mapred.pipes.Submitter.run(Submitter.java:503) at org.apache.hadoop.mapred.pipes.Submitter.main(Submitter.java:518 Would someone help me? -- Fernando
