After I upgrade my ORCH-1.1 to 2.0, I got an error like this when execute MapReduce via R:
DBG: 11:12:00 [ER] streaming JAR is not found at "/home/hadoop/hadoop-0.20.2/contrib/streaming/hadoop-0.20.2-streaming.jar"
Error: execution aborted
BTW, I have specified environment variable "*HADOOP_STREAMING_JAR*" and the file */home/hadoop/hadoop-0.20.2/contrib/streaming/hadoop-0.20.2-streaming.jar* exists.
Could you please give some advice?
