Description

Shutdown script (sending term signal) does not do a clean shutdown.

We are running kafka in kubernetes/openshift 0.11.0.0. The statefulset kafka runs the shutdown script prior to stopping the pod kafka is running on:

        lifecycle:
          preStop:
            exec:
              command:
              - ./bin/kafka-server-stop.sh

This worked perfectly in 0.11.0.0 but doesn't in 0.11.0.1. Also we see the same behaviour if we send a TERM signal to the kafka process (same as the shutdown script).
