----------------------------------
Summary: Null values in DECIMAL columns cause serialization issues
with HCatalog
Key: HIVE-7473
URL: https://issues.apache.org/jira/browse/HIVE-7473
Project: Hive
Issue Type: Bug
Components: Serializers/Deserializers
Affects Versions: 0.13.1
Reporter: Craig Condit
WritableHiveDecimalObjectInspector appears to be missing null checks in
getPrimitiveWritableObject(Object) and getPrimitiveJavaObject(Object). The same
checks do exist in WritableHiveVarcharObjectInspector.
Attempting to read from a table in HCatalog containing null values for decimal
columns results in the following exception (Pig used here):
