@astroshim That's not what I'm talking about. Assume the following:
Zeppelin run as user "zeppelin"
In `zeppelin-env.sh`: `export ZEPPELIN_IMPERSONATE_CMD='sudo -H -i -u
${ZEPPELIN_IMPERSONATE_USER} bash -c '`
User `zeppelin` have permission to execute paswordless sudo to local users
allowed to log into Zeppelin
Interpreters will with this run as the user starting the process, and the
zeppelin user will not have permission to send any signal to them.
My suggestion is to execute the `kill` with `$ZEPPELIN_IMPERSONATE_CMD` to
make sure the `kill` is executed in the same way as the interpreter was started
in the first place.
