Thanks for filing an issue. I think this isn't implemented and that the docs should be updated until it is. For comparison, `hash_count` is listed in the linked table as accepting "Any" input and is registered as: https://github.com/apache/arrow/blob/6f424d4df218d3e99cff44def99a9eb7ea180978/cpp/src/arrow/compute/kernels/hash_aggregate.cc#L3449-L3457 Note `InputType::Any()`. Whereas `hash_list` is only registered for primitive and not nested types and isn't registered similarly: https://github.com/apache/arrow/blob/6f424d4df218d3e99cff44def99a9eb7ea180978/cpp/src/arrow/compute/kernels/hash_aggregate.cc#L3679-L3689 I'm not sure if we have an issue to track this. cc @felipecrv to confirm -- This is an automated message from the Apache Git Service.
