> 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}
> Error: org.apache.pig.backend.executionengine.ExecException: ERROR 6018: Error converting
