----------------------------
Summary: HIVE: impossible to insert abs(0) in a decimal column in
a parquet's table
Key: HIVE-19085
URL: https://issues.apache.org/jira/browse/HIVE-19085
Project: Hive
Issue Type: Bug
Components: Hive
Affects Versions: 2.3.2
Reporter: ACOSS
Hi,
We use parquet's table to store the result of others query. Some query use the
function abs. If the function "abs" take 0 (type decimal) in input, then the
insert in the parquet's table failed
+Scenario:+
create table test (col1 decimal(10,2)) stored as parquet;
insert into test values(0);
insert into test select abs(col1) from test;
+Result;+
The insert query crash with the error:

Problem is probably due to the fastABS method. This method force "fastSignum"
to 1 even when the decimal is 0 (in this case "fastSignum" must be egal at 0).
Have a good day
