Review request for pig and Richard Ding.
Summary
-------
The below is my script :
register myanotherudf.jar;
A = load 'myinput' using PigStorage() as (
date:chararray,bcookie:chararray,count:int,avg:double,pvs:int);
B = foreach A generate (int)(avg / 100.0) * 100 as avg, pvs;
C = group B by ( avg );
D = foreach C {
Pvs = order B by pvs;
Const = org.vivek.MyAnotherUDF(Pvs.pvs).(count,sum);
generate Const.sum as sum;
};
store D into 'out_D';
The script is failing during compilation of the plan. The usage of the udf
inside the foreach is causing the problem. The udf implements algebraic and the
output schema is also defined.
The below is the exception that I get :
ERROR 2042: Error in new logical plan. Try -Dpig.usenewlogicalplan=false.
org.apache.pig.impl.logicalLayer.FrontendException: ERROR 2042: Error in new
logical plan. Try -Dpig.usenewlogicalplan=false.
