Hi, I am trying to run a java program as a mapper using Hadoop Streaming but getting the following error:
"Cannot run program "new_code.class": java.io.IOException: error=2, No such file or directory at java.lang.ProcessBuilder.start(ProcessBuilder.java:460)" The command being run is: /usr/bin/hadoop jar /usr/lib/hadoop/contrib/streaming/hadoop-streaming-1.0.2.jar -file /home/hadoop/zql/demo/api/new_code.class -mapper /home/hadoop/zql/demo/api/new_code.class -jobconf mapred.reduce.tasks=0 -input /rbbpoc/input/* -output /rbbpoc/output2001 The new_code.java program is running fine for me in a stand alone mode and is accepting stdin inputs. I have checked the permissions of the class file & they seem good. Any inputs to help resolve the above issue will be helpful.
