Not sure if there s a convenient way  but you can just inspect your kafka libs folder  You should see files like kafka 2 10-0 8 2-beta jar  where 2 10 is Scala version and 0 8 2-beta is Kafka version

You can grep the logs to see the version  Let s say kafka is installed under  usr local kafka  then     grep  Kafka version   usr local kafka logs     usr local kafka logs kafkaServer out  INFO Kafka version   0 9 0 1  org apache kafka common utils AppInfoParser    will reveal the version

To find the Kafka Version  We can use the jps command which show all the java processes running on the machine   Step 1  Let s say  you are running Kafka as the root user  so login to your machine with root and use jps -m  It will show the result like  4979 Jps -m 9434 Kafka config server properties   Step 2  From the above result  you can take the PID for Kafka application and use pwdx  9434 which reports the current directory of the process  the result will be like  9434   apps kafka 2 12-2 4 0   here you can see the Kafka version which is 2 12-2 4 0

There are several methods to find kafka version     Method 1 simple -   ps -ef grep kafka   it will displays all running kafka clients in the console    Ex -  usr hdp current kafka-broker bin    libs kafka-clients-0 10 0 2 5 3 0-37 jar we are using 0 10 0 2 5 3 0-37 version of kafka     Method 2 -   go to    cd  usr hdp current kafka-broker libs ll  grep kafka   Ex - kafka 2 10-0 10 0 2 5 3 0-37 jar kafka-clients-0 10 0 2 5 3 0-37 jar  same result as method 1 we can find the version of kafka using in kafka libs

go to kafka libs folder we can see multiple jars search for something similar  kafka 2 11-0 10 1 1 jar asc  in this case the kafka version is 0 10 1 1

I found an easy way to do this without searching directories or log files   kafka-dump-log --version   Output looks like this      5 3 0-ccs  Commit 6481debc2be778ee

There is nothing like kafka --version at this point  So you should either check the version from your kafka libs  folder or you can run  find   libs  -name   kafka      head -1   grep -o   kafka   n      from your kafka folder  and it will do the same for you   It will return you something like kafka 2 9 2-0 8 1 1 jar asc where 0 8 1 1 is your kafka version
