Hi Pig Users, I restate the question here: I run my Pig embedded program and get a strange outcome. This is the message from my console:
09/06/10 02:34:13 INFO executionengine.HExecutionEngine: Connecting to hadoop file system at: hdfs://localhost:9000 09/06/10 02:34:14 INFO executionengine.HExecutionEngine: Connecting to map-reduce job tracker at: localhost:9001 09/06/10 02:34:14 INFO mapReduceLayer.MRCompiler$LastInputStreamingOptimizer: Rewrite: POPackage->POForEach to POJoinPackage 09/06/10 02:34:14 INFO mapReduceLayer.MultiQueryOptimizer: MR plan size before optimization: 2 09/06/10 02:34:14 INFO mapReduceLayer.MultiQueryOptimizer: Merged 0 out of total 1 splittees. 09/06/10 02:34:14 INFO mapReduceLayer.MultiQueryOptimizer: MR plan size after optimization: 2 09/06/10 02:34:16 INFO mapReduceLayer.JobControlCompiler: Setting up single store job 09/06/10 02:34:16 WARN mapred.JobClient: Use GenericOptionsParser for parsing the arguments.

For some reason it write nothing into the output file. That's weird because I can run the same script in Grunt or PigPen and get a correct ouptut. Please help with your ideas. Thank you. George
