-----------------------------
Summary: pig can't sum with inner mutiply
Key: PIG-2754
URL: https://issues.apache.org/jira/browse/PIG-2754
Project: Pig
Issue Type: Bug
Components: internal-udfs
Affects Versions: 0.10.0
Environment: GNU bash, version 3.2.25(1)-release
(x86_64-redhat-linux-gnu)
Reporter: Mark Liu
sample code like that:
txns = LOAD '/test' USING PigStorage() AS (domain:chararray,amount:double);
txns_by_domain = GROUP txns BY domain;
test_txns = FOREACH txns_by_domain { domain = group; test_out =
SUM(txns.amount * txns.amount);}
...
it looks built-in function SUM did not support inner multiply and sum up.
