Hi Harsha Many thanks for responding.
As suggested, I have attempted to start kafka manually (which appeared to work), seconds later, a check of its status, and it is not running: [kafka@vortex01 ~]$ /usr/hdp/current/kafka-broker/bin/kafka start Starting Kafka succeeded with PID=104483. [kafka@vortex01 ~]$ /usr/hdp/current/kafka-broker/bin/kafka status Kafka is not running. With regards to files under kafka-broker/libs/kafka_*.jar: [kafka@vortex01 ~]$ find / -name "kafka_*jar" 2>/dev/null /usr/hdp/2.2.0.0-2041/ranger-hdfs-plugin/libs/kafka_2.10-0.8.1.2.2.0.0-2041.jar /usr/hdp/2.2.0.0-2041/ranger-hdfs-plugin/libs/kafka_2.10-0.8.1.2.2.0.0-2041-javadoc.jar /usr/hdp/2.2.0.0-2041/ranger-hdfs-plugin/libs/kafka_2.10-0.8.1.2.2.0.0-2041-sources.jar /usr/hdp/2.2.0.0-2041/ranger-hdfs-plugin/libs/kafka_2.10-0.8.1.2.2.0.0-2041-test.jar /usr/hdp/2.2.0.0-2041/ranger-hdfs-plugin/libs/kafka_2.10-0.8.1.2.2.0.0-2041-scaladoc.jar I will also raise this under http://hortonworks.com/community/forums/forum/kafka/ Regards Mark -----Original Message----- From: Harsha [mailto:ka...@harsha.io] Sent: 04 October 2015 16:42 To: users@kafka.apache.org Subject: Re: Kafka Broker process: Connection refused Mark, Can you try running the /usr/hdp/current/kafka- broker/bin/kafka start manually as user Kafka and also do you see jars under kafka-broker/libs/kafka_*.jar . Can you try asking the question here as well http://hortonworks.com/community/forums/forum/kafka/ Thanks, Harsha On Sun, Oct 4, 2015, at 01:49 AM, Mark Whalley wrote: > Hi Kafka List > > This is my first posting to this list, and I am relatively new to > Kafka so please accept my bear with me! > > Ambari Stack HDP-2.2 > Kafka .8.1.2.2.0.0 > Zookeeper 3.4.6.2.2.0.0 > > I have been using Kafka on a small (4 node) VM cluster running CentOS > 6.6 successfully for many months. > > > Following a recent cluster reboot, Kafka now refuses to work. > > From Ambari, all services start, then within seconds, Kafka Broker > stops with a “Kafka Broker process: Connection refused” > > /var/log/kafka/kafka.err reports: “Error: Could not find or load main > class kafka.Kafka” > > All other services appear to be working fine. > > The Ambari’s configuration reports that nothing has changed in the > configuration since May (Kafka was working until just over a week > ago).
