commit 1e8d99fc6972b98f0987dbf7b4209c08f3183976
Author: Joe McDonnell <[email protected]>
Date:   Fri Aug 8 18:58:33 2025 -0700    IMPALA-14147: Remove code for 
unsupported platforms
    
    In Impala 5, we decided to drop older unsupported platforms,
    specifically Centos 7, SLES 12, Ubuntu 16 and 18. These older
    platforms are holding up important upgrades due to an older
    OpenSSL (e.g. Python 3.10, OpenLDAP 2.5). They also increase
    the toolchain build time significantly. This removes the code
    for these platforms.
    
    Testing:
     - Ran a build without those platforms

> These operating system versions have all reached their respective 
> end-of-support dates as far as general support is concerned. All of them have 
> newer versions (some of them more than one) that are also supported by 
> Impala, so it is reasonable to expect that Impala users and contributors have 
> either upgraded their systems to a supported OS version, or they will do this 
> shortly.
> In the absence of generally available vendor support, it would also be hard 
> for Impala to maintain safe operations in case a vulnerability came along 
> that would not get fixed by the OS vendor claiming end of support for a 
> particular affected version.
> Based on the above reasoning I propose to remove support for these operating 
> system versions from the native-toolchain project, therefore from new binary 
> builds of the toolchain as well. Older toolchain builds will remain 
> accessible, and usable for older branches and versions of Impala; the 
> deprecation and removal will only impact the {{master}} branch, i.e. the 
> upcoming Impala 5.0.0 version.
