> This is related to ARROW-12010, which introduces optimized group by implementation.
> On s390x (big endian architecture) the code hangs in unit tests ([https://travis-ci.com/github/apache/arrow/jobs/506281680).]
> Currently this implementation is disabled on big endian and the alternative, earlier, implementation is used instead, but at some point we will stop maintaining both and switch to a single implementation, which requires fixing this issue.
