> The following script fail due to TableLoader class not found (If the jar is in classpath):
> {code}
> a = load '/user/pig/tests/data/zebra/singlefile/studentsortedtab10k' using org.apache.hadoop.zebra.pig.TableLoader('',
'sorted');
> b = load '/user/pig/tests/data/zebra/singlefile/votersortedtab10k' using org.apache.hadoop.zebra.pig.TableLoader('',
'sorted');
> g = cogroup a by $0, b by $0 using 'merge';
> store g into '/user/pig/out/jianyong.1304374720/ZebraMapCogrp_1.out';
> {code}
> If we use register, the error goes away. However, Pig always ship jars containing LoadFunc
automatically. It should be the same for merged cogroup/join.
