In 1.11.2/flinkSql/batch, tableEnv.getConfig.setNullCheck(false) seems to break group by-s

[Jon Alberdi]

Hello to all,

on flink-1.11.2 the program  written at https://gist.github.com/yetanotherion/d007fa113d97411226eaea4f20cd4c2d

creates unexpected stack traces when the line “// triggerBug…”

Is uncommented (some lines of the stack trace are written in the gist).

(It correctly outputs
“

+-------------+

|           c |

+-------------+

|           1 |

|           2 |

+-------------+

“ else)

Is that behavior expected?

If not, do you think a jira should be created to handle that? (I’d be glad to do so)

Regards,

Ion

Yes, I think this is a bug, feel free to open a jira and a pull request.

Hi Jon,

I would not recommend to use the configuration parameter. It is not
deprecated yet but can be considered legacy code from before we reworked
the type system.

Regards,
Timo
