Yongzhi Chen created HIVE-11112:
-----------------------------------
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 |
+-------------------+--+
