Hello Renato, the missing symbols says that Parquet is expecting the arrow functionality to be available using the new C++11 ABI. This typically points to the problem that arrow-cpp/parquet-cpp/pyarrow were built using different settings of _GLIBCXX_USE_CXX11_ABI on your system.
As in your case the C++ combination of arrow-cpp and parquet-cpp works, I would expect that in the setting with pyarrow, you have a different version of arrow-cpp also in the path. Thus your system default parquet-cpp also sees a different version of arrow-cpp which is incompatible to it. The best thing would be to check using ldd which libraries are loading when using pyarrow (e.g. by looking at ldd pyarrow/lib.so).
