Description

$ bin/kafka-configs.sh --bootstrap-server localhost:9092 --alter --add-config producer_byte_rate=1000000000,consumer_byte_rate=1000000000 --entity-type clients --entity-default

This usage of --entity-default with --bootstrap-server for alternating configs will trigger the exception below. Similar for --describe

/opt/kafka-dev/bin/kafka-configs.sh --bootstrap-server ducker04:9093 --describe --entity-type clients --entity-default --command-config /opt/kafka-dev/bin/hi.properties

Caused by: org.apache.kafka.common.errors.UnknownServerException: Path must not end with / character

However, if the --entity-type is brokers, the alternation works fine. 

$ No exception, works properly

bin/kafka-configs.sh --bootstrap-server localhost:9092 --entity-type brokers --entity-default --alter --add-config unclean.leader.election.enable=true

bin/kafka-configs.sh --bootstrap-server localhost:9092 --describe --entity-type brokers --entity-default

 

Update:

 

For --describe:

Commands work properly:

bin/kafka-configs.sh --bootstrap-server localhost:9092 --describe --entity-type brokers --entity-default

bin/kafka-configs.sh --zookeeper localhost:2181 --describe --broker-defaults

Commands do not work:

bin/kafka-configs.sh --bootstrap-server localhost:9092 --describe --entity-type topics --entity-default

bin/kafka-configs.sh --bootstrap-server localhost:9092 --describe --entity-type users --entity-default

bin/kafka-configs.sh --bootstrap-server localhost:9092 --describe --entity-type clients --entity-default

bin/kafka-configs.sh --bootstrap-server localhost:9092 --describe --client-defaults

bin/kafka-configs.sh --bootstrap-server localhost:9092 --describe --user-defaults

 

 

For --alter:

Commands work properly:

bin/kafka-configs.sh --zookeeper localhost:2181 --alter --add-config max.messages.bytes=128000 --entity-type topics --entity-default (an entity name must be specified with --alter of topics)

bin/kafka-configs.sh --bootstrap-server localhost:9092 --alter --add-config unclean.leader.election.enable=true --entity-type brokers --entity-default

 

Commands do not work:

bin/kafka-configs.sh --bootstrap-server localhost:9092 --alter --add-config producer_byte_rate=1000000000,consumer_byte_rate=1000000000 --entity-type clients --entity-default

bin/kafka-configs.sh --bootstrap-server localhost:9092 --alter --add-config producer_byte_rate=44444 --entity-type users --entity-default (No exception thrown but failed to add the config)

bin/kafka-configs.sh --bootstrap-server localhost:9092 --alter --add-config producer_byte_rate=1000000000,consumer_byte_rate=1000000000 --client-defaults

bin/kafka-configs.sh --bootstrap-server localhost:9092 --alter --add-config producer_byte_rate=44444 --user-defaults (No exception thrown but failed to add the config)
