Joris Van den Bossche commented on ARROW-12839:
-----------------------------------------------

[~amueller] sorry for the very late response.

It seems you are installing from source? (pip is not installing using a binary wheel? Which platform are you using?)

If installing from source, you need to ensure to enable HDFS while building (both for C++, see https://arrow.apache.org/docs/developers/cpp/building.html#optional-components ({{ARROW_HFDS}}) as for Python: {{export PYARROW_WITH_HDFS=1}})
