[jira] [Updated] (HIVE-7473) Null values in DECIMAL columns cause
serialization issues with HCatalog
[ https://issues.apache.org/jira/browse/HIVE-7473?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Craig Condit updated HIVE-7473:
-------------------------------
Description:
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):
{noformat}
