I'm trying to run a hadoop-streaming job, which runs a wine application using a bash shell script. When I run job, the system returns java.lang.NoSuchFieldError:  DEFAULT_MAPREDUCE_APPLICATION_CLASSPATH. I'm running CDH 5.3. Is this something that would show up if your are running hadoop-streaming MR1 vs MR2?   env hadoop jar /usr/lib/hadoop-mapreduce/hadoop-streaming.jar \ -D mapreduce.input.fileinputformat.split.minsize=1000737418240 \ -D mapreduce.job.reduces=0 \ -input hdfs://xdata/data/nxcore/*.XA.nxc \ -output hdfs://xdata/data/nxcore/processed \ -mapper nxprocess.sh \ -file /home/nxcore/.wine/drive_c/Projects/nxcore/nxprocess.sh \ -verbose  I get the following error:   15/02/06 16:20:18 INFO mapreduce.JobSubmitter: number of splits:5 15/02/06 16:20:18 INFO mapreduce.JobSubmitter: Submitting tokens for job: job_1419361536499_0082 15/02/06 16:20:18 INFO mapreduce.JobSubmitter: Cleaning up the staging area /user/nxcore/.staging/job_1419361536499_0082 Exception in thread "main" java.lang.NoSuchFieldError: DEFAULT_MAPREDUCE_APPLICATION_CLASSPATH at org.apache.hadoop.mapreduce.v2.util.MRApps.setMRFrameworkClasspath(MRApps.java:218) at org.apache.hadoop.mapreduce.v2.util.MRApps.setClasspath(MRApps.java:250) at org.apache.hadoop.mapred.YARNRunner.createApplicationSubmissionContext(YARNRunner.java:460) at org.apache.hadoop.mapred.YARNRunner.submitJob(YARNRunner.java:284) at org.apache.hadoop.mapreduce.JobSubmitter.submitJobInternal(JobSubmitter.java:407) at org.apache.hadoop.mapreduce.Job$11.run(Job.java:1269) at org.apache.hadoop.mapreduce.Job$11.run(Job.java:1266) 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:1642) at org.apache.hadoop.mapreduce.Job.submit(Job.java:1266) at org.apache.hadoop.mapred.JobClient$1.run(JobClient.java:606) at org.apache.hadoop.mapred.JobClient$1.run(JobClient.java:601) 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:1642) at org.apache.hadoop.mapred.JobClient.submitJobInternal(JobClient.java:601) at org.apache.hadoop.mapred.JobClient.submitJob(JobClient.java:586) at org.apache.hadoop.streaming.StreamJob.submitAndMonitorJob(StreamJob.java:1014) at org.apache.hadoop.streaming.StreamJob.run(StreamJob.java:135) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:84) at org.apache.hadoop.streaming.HadoopStreaming.main(HadoopStreaming.java:50) 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:212) TIA,   Matt         ...
