Apache Kafka 0.8 log4j2.xml Appender bekommen Timeout Fehler

Question

Ich muss Kafka Appender mit log4j2.xml konfigurieren, das Setup funktionierte gut lokal, aber Server bekomme ich unter Fehler.

Lokale Kafka: kafka_2.11-0.10.2.0

Kafka Appender: 0.9.0.0 Local hat gut funktioniert.

Server Kafka: 0,8

Kafka Appender: 0.9.0.0

Auf dem Server ich folgende Fehlermeldung bekam:

Answer 1

Meine schlechte, schrieb ich Wert für bootstrap.servers -Eigenschaft mit extra Leerzeichen in log4j2.xml, nach rem Durch den Raum konnte ich mich mit Kafka verbinden. Vielen Dank.

Answer 2

Sie sind nicht in der Lage, die Metadaten zu erhalten, prüfen Sie, ob der kafka Cluster ist betriebsbereit und es gibt keine Konnektivitätsproblem
