             Summary: Docker image build script fails to set the sticky bit for /var/tmp when building on top of a Wolfi base image
                 Key: IMPALA-13937
                 URL: https://issues.apache.org/jira/browse/IMPALA-13937
             Project: IMPALA
          Issue Type: Bug
    Affects Versions: Impala 5.0.0
            Reporter: Laszlo Gaal
            Assignee: Laszlo Gaal


The Docker base image build script {{docker/install_os_packages.sh}} attempts to set the sticky bit (+t) on /tmp and on /var/tmp to support using Kerberos with Impala.
Unfortunately the version of {{chmod}} that is bundled in the Wolfi base images is based on {{busybox}}, and it seems to ignore the user-friendly syntax used in the above shell script. This causes the {{chmod}} command to drop the sticky bit silently, withouh even reporting an error; but the sticky bit is never applied to these directories.
Later, when the images are activated in an environment using Kerberos, this prevents Impala daemons from starting up, as the code contains an explicit check requiring this permission.
