Hi again, Now I'm having a problem where, after JOINing 2 relations, I can't get an ILLUSTRATE to work on the resulting relation (though a DUMP is working just fine). The error produced is:
2010-12-09 00:10:52,076 [main] INFO org.apache.hadoop.metrics.jvm.JvmMetrics - Cannot initialize JVM Metrics with processName=JobTracker, sessionId= - already initialized 2010-12-09 00:10:52,723 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2999: Unexpected internal error. null Details at logfile: /home/kris/pig_1291831812543.log the relation in question is the result of x1 = JOIN y6 BY uid, z4 BY uid; where y6 ilustrates as: ----------------------------------------------- | y6 | uid: chararray | installTime: int | ----------------------------------------------- | | 100000257874171 | 1265951856 | | | 697239231 | 1265954100 | ----------------------------------------------- and z4 illustrates as: --------------------------------------------------------- | z4 | uid: chararray | timestamp: int | value: int | --------------------------------------------------------- | | 790470383 | 1270762540 | 300 | --------------------------------------------------------- (and both y6 and z4 have been produced by a pipeline which includes a filter requiring (uid is not null) ). Any ideas what might help make this work? Thanks, Kris -- Kris Coward http://unripe.melon.org/ GPG Fingerprint: 2BF3 957D 310A FEEC 4733 830E 21A4 05C7 1FEB 12B3
