             Summary: ISO-8859-1 text output has fragments of previous longer rows appended
                 Key: HIVE-11112
                 URL: https://issues.apache.org/jira/browse/HIVE-11112
             Project: Hive
          Issue Type: Bug
          Components: Serializers/Deserializers
    Affects Versions: 1.2.0
            Reporter: Yongzhi Chen
            Assignee: Yongzhi Chen


If a LazySimpleSerDe table is created using ISO 8859-1 encoding, query results for a string column are incorrect for any row that was preceded by a row containing a longer string.

Example steps to reproduce:

1. Create a table using ISO 8859-1 encoding:

CREATE TABLE person_lat1 (name STRING)
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe' WITH SERDEPROPERTIES ('serialization.encoding'='ISO8859_1');

2. Copy an ISO-8859-1 encoded text file into the appropriate warehouse folder in HDFS. I'll attach an example file containing the following text: 

Müller,Thomas
Jørgensen,Jørgen
Peña,Andrés
Nåm,Fæk

3. Execute SELECT * FROM person_lat1

Result - The following output appears:

+-------------------+--+
| person_lat1.name |
+-------------------+--+
| Müller,Thomas |
| Jørgensen,Jørgen |
| Peña,Andrésørgen |
| Nåm,Fækdrésørgen |
+-------------------+--+
