Hi 
Recently, I have upgraded confluent kafka cluster to 5.5.1-ce (Commit:43158bb473a722bd) and trying to start broker nodes one by one with the command  kafka-server-start. However, i am getting following error related to license.

org.apache.kafka.common.KafkaException: Failed to start license store with topic _confluent-license. A valid license must be configured using 'confluent.license' if topic is unavailable.
        at io.confluent.license.validator.ConfluentLicenseValidator.start(ConfluentLicenseValidator.java:138)
        at kafka.server.KafkaServer.startup(KafkaServer.scala:532)
        at io.confluent.support.metrics.SupportedServerStartable.startup(SupportedServerStartable.java:140)
        at io.confluent.support.metrics.SupportedKafka.main(SupportedKafka.java:66)

It looks like, i need a valid license to run a confluent kafka cluster.

Shall i have to buy a license from Confluent to run cluster of confluent kafka (community) broker/worker ?

Regards

-ce indicates that you are using Confluent Enterprise, which requires a license.

Sounds like you want Confluent Community Server (-ccs) which does not require a license.

Correct. One might think -ce suffix indicates community edition like it does in the rest of the known universe but for Confluent it does in fact indicate Confluent Enterprise aka Confluent Platform (CP)

Hi
Many thanks for correcting me (CE and CCS ). My cluster is now up with CCS.
Regards
