------------------------------------
Summary: Bad Test in OrcColumnarRowSplitReaderTest
Key: FLINK-31880
URL: https://issues.apache.org/jira/browse/FLINK-31880
Project: Flink
Issue Type: Bug
Components: Connectors / ORC, Formats (JSON, Avro, Parquet, ORC,
SequenceFile)
Reporter: Kurt Ostfeld
This is a development issue with, what looks like a buggy unit test.
I tried to build Flink with a clean copy of the repository and I get:
```
[INFO] Results:
[INFO]
[ERROR] Failures:
[ERROR] OrcColumnarRowSplitReaderTest.testReadFileWithTypes:365
expected: "1969-12-31"
but was: "1970-01-01"
[INFO]
[ERROR] Tests run: 26, Failures: 1, Errors: 0, Skipped: 0
```
I see the test is testing Date data types with `new Date(562423)` which is 9
minutes and 22 seconds after the epoch time, which is 1970-01-01 UTC time, or
when I run that on my laptop in CST timezone, I get `Wed Dec 31 18:09:22 CST
1969`.
I have a simple pull request ready which fixes this issue and uses the Java 8
LocalDate API instead which avoids time zones entirely.
