-----------------------------------
Summary: Test data generation failure in HIVE-28249 related tests
Key: HIVE-28273
URL: https://issues.apache.org/jira/browse/HIVE-28273
Project: Hive
Issue Type: Bug
Reporter: Csaba Juhász
Attachments: image-2024-05-22-19-11-35-890.png
generateJulianLeapYearTimestamps and generateJulianLeapYearTimestamps28thFeb
are throwing NegativeArraySizeException once the base value equals or is over
999
This is caused by the below code, supplying a negative value (when digits
return a value larger than 4) to zeros, which in turn is used to create a new
char array.
{code:java}
StringBuilder sb = new StringBuilder(29);
int year = ((i % 9999) + 1) * 100;
sb.append(zeros(4 - digits(year)));
{code}
When the tests are run using maven, the error in the generation function is
caught but never rethrown or reported and the build is reported successful.
For example running
_TestParquetTimestampsHive2Compatibility#testWriteHive2ReadHive4UsingLegacyConversionWithJulianLeapYearsFor28thFeb_
has the result:
{code:java}
