I have a pig script, that activates another python program.
I was able to do so in my own hadoop environment, but I always fail when I run my script in Amazon map reduce WS.

The log say:

org.apache.pig.backend.executionengine.ExecException: ERROR 2090: Received Error while processing the reduce plan: ” failed with exit status: 127
at org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.PigMapReduce$Reduce.runPipeline(PigMapReduce.java:347)

at org.apache.hadoop.mapred.ReduceTask.run(ReduceTask.java:321)
at org.apache.hadoop.mapred.TaskTracker$Child.main(TaskTracker.java:2216)

Any Idea?
