ok. so there you go. IMO, you're going to have to create a custom wrapper
around hive so that your users find your wrapper (via PATH) before they
find the real hive executable.
Your wrapper checks for whatever you deem acceptable and if so calls the
real hive else errors out with your message.
pseudo-code:
#!/bin/bash
if [[ $#-eq 0 ]]; then
echo "your message"
exit 1;
else
exec /path/to/real/hive $@
fi
there are other edge cases you may want to consider. "hive -service cli"
would pass and you wouldn't want that but you get the idea i presume.
