How to find the kafka version in linux - apache-kafka

Question

How to find the kafka version in linux?
whether there is a way to find the installed kafka version other than mentioning the version while downloading it?

Answer 1

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.

Answer 2

Kafka 2.0 have the fix(KIP-278) for it:
kafka-topics.sh --version
Or
kafka-topics --version
Using confluent utility:
Kafka version check can be done with confluent utility which comes by default with Confluent platform(confluent utility can be added to cluster separately as well - credits cricket_007).
${confluent.home}/bin/confluent version kafka
Checking the version of other Confluent platform components like ksql schema-registry and connect
[confluent-4.1.0]$ ./bin/confluent version kafka
1.1.0-cp1
[confluent-4.1.0]$ ./bin/confluent version connect
4.1.0
[confluent-4.1.0]$ ./bin/confluent version schema-registry
4.1.0
[confluent-4.1.0]$ ./bin/confluent version ksql-server
4.1.0

Answer 3

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.

Answer 4

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.

Answer 5

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

Answer 6

If you want to check the version of a specific Kafka broker, run this CLI on the broker*
kafka-broker-api-versions.sh --bootstrap-server localhost:9092 --version
where localhost:9092 is the accessible <hostname|IP Address>:<port> this API will check (localhost can be used if it's the same host you're running this command on). Example of output:
2.4.0 (Commit:77a89fcf8d7fa018)
* Apache Kafka comes with a variety of console tools in the ./bin sub-directory of your Kafka download; e.g. ~/kafka/bin/

Answer 7

Simple way on macOS e.g. installed via homebrew
$ ls -l $(which kafka-topics)
/usr/local/bin/kafka-topics -> ../Cellar/kafka/0.11.0.1/bin/kafka-topics

Answer 8

You can use for Debian/Ubuntu:
dpkg -l|grep kafka
Expected result should to be like:
ii confluent-kafka-2.11 0.11.0.1-1 all publish-subscribe messaging rethought as a distributed commit log
ii confluent-kafka-connect-elasticsearch 3.3.1-1 all Kafka Connect connector for copying data between Kafka and Elasticsearch
ii confluent-kafka-connect-hdfs 3.3.1-1 all Kafka Connect connector for copying data between Kafka and Hadoop HDFS
ii confluent-kafka-connect-jdbc 3.3.1-1 all Kafka Connect connector for JDBC-compatible databases
ii confluent-kafka-connect-replicator 3.3.1-1 all Kafka Connect connector for replicating topics between Kafka clusters
ii confluent-kafka-connect-s3 3.3.1-1 all Kafka Connect S3 connector for copying data between Kafka and
ii confluent-kafka-connect-storage-common 3.3.1-1 all Kafka Connect Storage Common contains packages used by storage
ii confluent-kafka-rest 3.3.1-1 all A REST proxy for Kafka

Answer 9

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

Answer 10

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)

Answer 11

cd kafka
./bin/kafka-topics.sh --version

Answer 12

When you install Kafka in Centos7 with confluent :
yum install confluent-platform-oss-2.11
You can see the version of Kafka with :
yum deplist confluent-platform-oss-2.11
You can read : confluent-kafka-2.11 >= 0.10.2.1

Answer 13

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
