Hi, I use kafka.tools.ConsumerOffsetChecker to view the consumer offset status, and can get the correct output, along with a warning: ConsumerOffsetChecker is deprecated and will be dropped in releases following 0.9.0. Use ConsumerGroupCommand instead.
But when I altered to bin/kafka-run-class.sh kafka.admin.ConsumerGroupCommand --zookeeper 127.0.0.1:2181 --list, there was nothing to output. Did I missed some parameters to run ConsumerGroupCommand? The version is kafka _2.11-0.9.0.0, and any suggestion is appreciated.
