Hi all first, sorry if this has been asked before, but could not find any reference in the list archives.
I have tried to run the PigUnit example (top_queries.pig) provided on http://pig.apache.org/docs/r0.8.1/pigunit.html on my 64-bit MacOS 10.6. I have built and deployed the 0.9.0 jars via maven but I get: ... 11/08/11 10:43:10 INFO mapred.MapTask: io.sort.mb = 100 11/08/11 10:43:10 INFO mapReduceLayer.MapReduceLauncher: HadoopJobId: job_local_0001 11/08/11 10:43:10 INFO mapReduceLayer.MapReduceLauncher: 0% complete 11/08/11 10:43:10 WARN mapred.LocalJobRunner: job_local_0001 java.lang.OutOfMemoryError: Java heap space at org.apache.hadoop.mapred.MapTask$MapOutputBuffer.<init>(MapTask.java:781) at org.apache.hadoop.mapred.MapTask$NewOutputCollector.<init>(MapTask.java:524) at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:613) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:305) at org.apache.hadoop.mapred.LocalJobRunner$Job.run(LocalJobRunner.java:177) 11/08/11 10:43:15 INFO mapReduceLayer.MapReduceLauncher: job job_local_0001 has failed!

Stats reported below may be incomplete 11/08/11 10:43:15 INFO pigstats.SimplePigStats: Script Statistics: I find it very hard to believe that I have run out of heap space processing 10 lines of input. I have searched and searched online and there was one entry that seemed to indicate that the issue "may" be MacOS specific but no solution or work around given. Any input on this highly appreciated. Cheers Sotos
