explain and dump not working with two UDFs inside inner plan of foreach
-----------------------------------------------------------------------
Key: PIG-1030
URL: https://issues.apache.org/jira/browse/PIG-1030
Project: Pig
Issue Type: Bug
Reporter: Ying He
this scprit does not work
register /homes/yinghe/owl/string.jar;
a = load '/user/yinghe/a.txt' as (id, color);
b = group a all;
c = foreach b {
d = distinct a.color;
generate group, string.BagCount2(d), string.ColumnLen2(d, 0);
}
the udfs are regular, not algebraic.
then if I call "dump c;" or "explain c", I would get this error message.
ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2019: Expected to find plan with
single leaf. Found 2 leaves.
The error only occurs forn the first time, after getting this error, if I call
"dump c" or "explain c" again, it would succeed.
