HDP 2.6 uses Kafka 0.10.0: https://github.com/apache/ambari/blob/branch-2.6/ambari-server/src/main/resources/stacks/HDP/2.6/services/KAFKA/metainfo.xml#L23
The version number which you are seeing is a combination of the HDP stack version (2.6.1.0-129) along with the Apache version of Kafka which is included (0.10.1). If you were trying to install HDP 2.6.2.2, then you must have used the wrong repo since 2.6.1.0-129 was installed. Either way, you're still going to get Kafka 0.10.1 On 1/11/19, 6:48 AM, "Jacek Szewczyk" <jacek7...@gmail.com> wrote: Hey ! I am confused by Ambari kafka version, after installing 2.6.2.2 in Admin -> Stack and Versions I have kafka 1.0.0 so I expected that’s the version kafka was installed, but in reality it is: kafka_2_6_1_0_129-0.10.1.2.6.1.0-129.noarch Any ideas why that’s the case?
