---------------------------------
Summary: The result of TimestampWritableV2.toString() is wrong
when year is larger than 9999.
Key: HIVE-24748
URL: https://issues.apache.org/jira/browse/HIVE-24748
Project: Hive
Issue Type: Bug
Components: Serializers/Deserializers
Affects Versions: All Versions
Environment: Master branch
Reporter: Qiang.Kang
Hi, I found that `TimestampWritableV2.toString()` can be wrong when year is
larger than 9999. Here is what I get:
- test code:
```java
@Test
publicvoidtestTimestampWritableV2toString() {
TimestampWritableV2timestampWritableV2 = newTimestampWritableV2(
Timestamp.valueOf("10001-01-01 01:01:23"));
assertEquals("+10001-01-01 01:01:23", timestampWritableV2.toString());
}
```
- output:
```
org.junit.ComparisonFailure:
Expected :+10001-01-01 01:01:23
Actual :+10001-01-01 01:01:2323
```
The patch below removes some 'wrong' code in `TimestampWritableV2.toString()`,
for the reason that the length of
`org.apache.hadoop.hive.common.type.Timestamp#toString` can be larger than 19,
even its nano-of-second is zero.
