Description

Recent versions of Redhat UBI7 have shipped without setting the sticky bit on /var/tmp and /tmp. i.e.

7.9-861:
$ ls -l /var
drwxrwxrwx  2 root root 4096 Oct 27 13:15 tmp

7.9-8291666711770:
$ ls -l /var
drwxrwxrwx  2 root root 4096 Oct 25 18:28 tmp

7.9-8291665060345:
$ ls -l /var
drwxrwxrwt  2 root root 4096 Oct  6 13:02 tmp

Impala checks that the sticky bit is set on /var/tmp and will fail startup if it is not set. We should set the sticky bit in Docker build as a workaround. As a separate item, we can investigate whether the sticky bit is still necessary.
