This is suspicious
```
/home/vibhatha/github/forks/twisterx/ENVTX/lib/python3.8/site-packages/pyarrow/libarrow_python.so.16
```
If I had to guess you have many versions of Arrow on your system, including one that is pre-0.15
If the libraries are located in site-packages/pyarrow then there is no need to put the libraries in your LD_LIBRARY_PATH. Indeed, please open a JIRA and provide more detail about exactly how you built the C++ and Python libraries and how you modified your environment variables
