Hi all,
I installed kafka_2.11-2.0.0 tarball on a CentOS server :
[kafka@oxelkk-bo-1:~] $ uname -a
Linux oxelkk-bo-1 3.10.0-862.11.6.el7.x86_64 #1 SMP Tue Aug 14 21:49:04 UTC
2018 x86_64 x86_64 x86_64 GNU/Linux
[kafka@oxelkk-bo-1:~] $
equipped with this JVM:
[kafka@oxelkk-bo-1:~] $ java -version
java version "1.8.0_77"
Java(TM) SE Runtime Environment (build 1.8.0_77-b03)
Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)
[kafka@oxelkk-bo-1:~] $
I have a strange behavior of the utility bin/kafka-consumer-groups.sh when it
is called with --zookeeper option, like:
[kafka@oxelkk-bo-1:~] $
/store1/elk/run/kafka_2.11-2.0.0/bin/kafka-consumer-groups.sh --zookeeper
oxelkk-bo-1.iol.local:2181 --list
Exception in thread "main" joptsimple.UnrecognizedOptionException: zookeeper is
not a recognized option

[kafka@oxelkk-bo-1:~] $
Whilst if I use (just for a test) the same utility coming with
kafka_2.11-0.11.0.0, I have the expected response (the groups are related to
two Druid Tranquility tasks):
[kafka@oxelkk-bo-1:~] $
/store1/elk/run/kafka_2.11-0.11.0.0/bin/kafka-consumer-groups.sh --zookeeper
oxelkk-bo-1.iol.local:2181 --list
Note: This will only show information about consumers that use ZooKeeper (not
those using the Java consumer API).
tranquility-kafka-proxy
tranquility-kafka-ssoeven
[kafka@oxelkk-bo-1:~] $
I noticed that the documentation for Kafka 2.0.0 at:
https://kafka.apache.org/documentation/#basic_ops_consumer_lag states:
This tool also works with ZooKeeper-based consumers:
bin/kafka-consumer-groups.sh --zookeeper localhost:2181 --describe --group
my-group
Do you have any hint on this behavior?
Thank you very much,
Marco Spadoni
