[GitHub] [pinot] chimucong opened a new issue #8020: pinot-druid-benchmark fails
chimucong opened a new issue #8020:
URL: https://github.com/apache/pinot/issues/8020
I ran into trouble when running the benchmark.
When importing the TPC-H data, the exception occurs:
```bash
java.lang.RuntimeException: Caught exception while transforming data type for column: l_comment
...
Caused by: java.lang.IllegalArgumentException: Cannot read single-value from Object[]: [y express dolphins use blithely, s] for column: l_comment
...
```
The corresponding row in TPC-H data that causes this exception is
```text
21339361|1373339|73391|4|29|40955.83|0.04|0.04|A|F|1992-01-02|1992-03-14|1992-01-19|DELIVER IN PERSON|MAIL|y express dolphins use blithely; s|
```
which has a semicolon in the `l_comment` column.
For `org.apache.pinot.plugin.inputformat.csv.CSVRecordReaderConfig`, `multiValueDelimiterEnabled` is set to `true` by default, and the `DEFAULT_MULTI_VALUE_DELIMITER` is `;`.
To avoid the `l_comment` being parsed as multiple values, the `multiValueDelimiterEnabled` has to be set to `true` explicitly in the job-spec.yml file.
The corresponding PR is https://github.com/apache/pinot/pull/8012 .

Good catch. Thanks for contributing the fix. This is a very old benchmark (almost 5 years) and not being actively maintained. Please let us know if you run into more issues
