Description

Currently Ozone relies on HADOOP_* environment variables (eg. HADOOP_HOME) for historical and practical reasons (code reuse). If Hadoop and Ozone are both present on a node, and they share their environment, then ozone (and stop-ozone.sh) exits with error:

$ ozone help
ERROR: Cannot execute /usr/local/hadoop/libexec/ozone-config.sh.

The same problem was reported and fixed in HDDS-1912 for the start-ozone.sh script. This task is limited to applying the changes from HDDS-1912 to the other two scripts. Ideally Ozone should use its own environment variables, which is a much larger change.
