While restarting the PySpark server, I see the following warning message: "UserWarning: Could not import the lzma module. Your installed Python is incomplete", how can I resolve this issue?

Setup & Configuration Python Installation
1

This warning occurs when Python is built without the required lzma support. To resolve this issue on CentOS systems, install the necessary development package and recompile Python from source.

  1. Install the required dependency:

    sudo yum install -y xz-devel

  2. Recompile python from source code:

    cd Python-3.6.5
    sudo ./configure --enable-optimizations
    sudo make altinstall

After recompiling, restart the PySpark server and verify that the warning no longer appears.
