In the python binding (pyarrow) the `hash_*` functions are not implemented
to be called directly.
If you use a development version of pyarrow you could do something like this:
``` python
import pyarrow as pa
import pyarrow.compute as pc
table = pa.table([[1, 2, 3],["a", "b", "a"]], names=["values", "keys"])
table.group_by("keys").aggregate([("values","hash_sum")])
```
and you would get:
```
pyarrow.Table
values_sum: int64
keys: string
----
values_sum: [[4,2]]
keys: [["a","b"]]
```
