The intent of this part of accumulo-env.sh is to allow having different java
config for different set of compactors. Like if compactor groups `q1` and `q2`
were defined in cluster.yaml then could give processes in those two compactor
groups different memory setting w/ the following config. Maybe some comments
need to be added to the default `accumulo-env.sh` to explain this.
```bash
case "${ACCUMULO_RESOURCE_GROUP:-default}" in
q1)
case "$cmd" in
compactor) JAVA_OPTS=('-Xmx16G' '-Xms256m' "${JAVA_OPTS[@]}") ;;
esac
;;
q2)
case "$cmd" in
compactor) JAVA_OPTS=('-Xmx1G' '-Xms256m' "${JAVA_OPTS[@]}") ;;
esac
;;
default)
# shellcheck disable=SC2154
# $cmd is exported in the accumulo script, but not the accumulo-service
script
case "$cmd" in
manager | master) JAVA_OPTS=('-Xmx512m' '-Xms512m' "${JAVA_OPTS[@]}")

exit 1
