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
