----------------------------------

             Summary: NPE when an empty file is included in a Hive query that 
uses CombineHiveInputFormat
                 Key: PARQUET-19
                 URL: https://issues.apache.org/jira/browse/PARQUET-19
             Project: Parquet
          Issue Type: Bug
            Reporter: Matt Martin


Make sure the valueObj instance variable is always initialized.  This change is 
neeeded when running a Hive query that uses the CombineHiveInputFormat and the 
first file in the combined split is empty.  This can lead to a 
NullPointerException because the valueObj is null when the 
CombineHiveInputFormat calls the createValue method.
