illustrate fails after join
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

Illustrate in the current version of the pig is likely to be broken as we have not been actively maintaining it for a while. We are fixing it now and it will become part of Pig 0.9 release.
