J'en ai un :
- une seule instance d'Apache Kafka (2.9.2-0.8.1.1) installée à partir de la source, en utilisant la configuration par défaut (
server.properties
etc.), - Zookeeper (3.4.5+dfsg-2) stand-alone, installé depuis le package
fonctionnant sur un hôte Ubuntu 14.04 LTS avec un nom hostname1
.
J'essaie d'arrêter Kafka proprement mais je n'y arrive pas.
J'ai essayé 2 méthodes :
-
envoi de SIGINT - mais Kafka l'ignore tout simplement (il ne mentionne pas la réception du signal dans un quelconque journal, il continue à fonctionner) [SIGTERM fonctionne mais ce n'est pas le sujet].
-
en utilisant Outil d'arrêt contrôlé - mais il échoue avec ce qui suit..
