I have a:
- single instance of Apache Kafka (2.9.2-0.8.1.1) installed from the source, using the default configuration (
server.properties
etc.), - Zookeeper (3.4.5+dfsg-2) stand-alone, installed from the package
..running on a Ubuntu 14.04 LTS host with a name hostname1
.
I try to shutdown Kafka cleanly but I can't.
I tried 2 methods:
sending SIGINT - but Kafka simply ignores it (doesn't mention recieving the signal in any log, keeps running) [SIGTERM works but that's not the point]
using Controlled Shutdown tool - but it fails with the following..
..stacktrace:

For 0.8.1.1 this tool:
Quote from "Controlled shutdown tool doesn't seem to work out of the box" Kafka JIRA issue:
Here is what I ended up putting into my
config/server.properties
:First thing is that I have used the wrong signal. I should have used SIGTERM (15) instead of SIGINT (2).
Second is that as @MaasSql have pointed out, you have to explicitely turn on controlled shutdown in Kafka 0.8.1.1.
(For 0.8.2+ you don't have do that - it is enabled by default.)
