Hi All,

I got the error below while running "cd python/ && python setup.py build_ext 
--inplace", after successfully building and installing a recent master version 
(a63e60bad89b41266d155bc496eb383765702492) of Arrow C++ under a pyarrow-dev 
Conda environment, as in the Python dev doc 
(https://arrow.apache.org/docs/developers/python.html). I didn't have a problem 
with this environment until now. Anyone have an idea how to fix the error?

CMake Error at 
/miniconda3/envs/pyarrow-dev/lib/cmake/Parquet/ParquetConfig.cmake:65 
(arrow_keep_backward_compatibility):
  Unknown CMake command "arrow_keep_backward_compatibility".
Call Stack (most recent call first):

Cheers,
