------------------------------------

             Summary: Deprecate and remove CentOS 7, Ubuntu 16.04, Ubuntu 18.04 and SLES 12 support from the toolchain
                 Key: IMPALA-14147
                 URL: https://issues.apache.org/jira/browse/IMPALA-14147
             Project: IMPALA
          Issue Type: Improvement
          Components: Toolchain
    Affects Versions: Impala 5.0.0
            Reporter: Laszlo Gaal


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.
