On RHEL/CentOS you might encounter an exception when trying to stop or restart Oozie :
resource_management.core.exceptions.Fail: Execution of 'cd /var/tmp/oozie && /usr/hdp/current/oozie-server/bin/oozie-stop.sh' returned 1. -bash: line 0: cd: /var/tmp/oozie: No such file or directory
This is likely because of a shell crontab /etc/cron.daily/tmpwatch which delete files/directories unmodified for 30d+
[root@local ~]# cat /etc/cron.daily/tmpwatch
#! /bin/sh
flags=-umc
/usr/sbin/tmpwatch "$flags" -x /tmp/.X11-unix -x /tmp/.XIM-unix \
-x /tmp/.font-unix -x /tmp/.ICE-unix -x /tmp/.Test-unix \
-X '/tmp/hsperfdata_*' 10d /tmp
/usr/sbin/tmpwatch "$flags" 30d /var/tmp
for d in /var/{cache/man,catman}/{cat?,X11R6/cat?,local/cat?}; do
if [ -d "$d" ]; then
/usr/sbin/tmpwatch "$flags" -f 30d "$d"
fi
done
