Hi, Guozhang Thank you very much for the reply, as you mentioned, I download the latest version
https://www.apache.org/dyn/closer.cgi?path=/kafka/0.8.2-beta/kafka-0.8.2-beta-src.tgz Untar this build and here is what I see root@DO-mq-dev:/home/stuser/kafka-0.8.2-beta-src/bin# kafka-console-consumer.sh The console consumer is a tool that reads data from Kafka and outputs it to standard output. Option Description ------ ----------- --blacklist <blacklist> Blacklist of topics to exclude from consumption. --consumer.config <config file> Consumer config properties file. --csv-reporter-enabled If set, the CSV metrics reporter will be enabled --delete-consumer-offsets If specified, the consumer path in zookeeper is deleted when starting up --formatter <class> The name of a class to use for formatting kafka messages for display. (default: kafka.tools. DefaultMessageFormatter) --from-beginning If the consumer does not already have an established offset to consume from, start with the earliest message present in the log rather than the latest message. --max-messages <Integer: num_messages> The maximum number of messages to consume before exiting. If not set, consumption is continual. --metrics-dir <metrics dictory> If csv-reporter-enable is set, and this parameter isset, the csv metrics will be outputed here --property <prop> --skip-message-on-error If there is an error when processing a message, skip it instead of halt. --topic <topic> The topic id to consume on. --whitelist <whitelist> Whitelist of topics to include for consumption. --zookeeper <urls> REQUIRED: The connection string for the zookeeper connection in the form host:port. Multiple URLS can be given to allow fail-over. Again, I am still not able to see description of --property, or I download the wrong version? thanks AL On Tue, Feb 3, 2015 at 4:29 PM, Guozhang Wang <wangg...@gmail.com> wrote: > Hello Sa, > > Could you try the latest 0.8.2 release, whose console consumer tool has > been polished a bit with clearer properties? > > Guozhang > > > On Tue, Feb 3, 2015 at 10:32 AM, Sa Li <sal...@gmail.com> wrote: > > > GuoZhang > > > > Sorry for leaving this topic for a while, I am still not clear how to > > commit the offset to zk from commandline, I tried this > > > > bin/kafka-console-consumer.sh --zookeeper 10.100.71.33:2181 --topic > > pipe-test-2 --from-beginning --property pipe > > > > It seems generate a console-consumer-001 in zK, but when I did that to > > other topics, nothing in zk, (I can't read anything from consumer group > in > > kafka-web-console), see > > [zk: localhost:2181(CONNECTED) 2] ls > /consumers/web-console-consumer-38650 > > [offsets, owners, ids] > > [zk: localhost:2181(CONNECTED) 3] ls > > /consumers/web-console-consumer-38650/offsets > > [PofApiTest-1] > > [zk: localhost:2181(CONNECTED) 4] ls > > /consumers/web-console-consumer-38650/offsets/PofApiTest-1 > > [3, 2, 1, 0, 7, 6, 5, 4] > > [zk: localhost:2181(CONNECTED) 5] ls > > /consumers/web-console-consumer-38650/offsets/PofApiTest-1/3 > > [] > > > > Any ideas? > > > > thanks > > > > AL > > > > > > On Tue, Jan 20, 2015 at 9:57 PM, Guozhang Wang <wangg...@gmail.com> > wrote: > > > > > It seems not the latest version of Kafka, which version are you using? > > > > > > On Tue, Jan 20, 2015 at 9:46 AM, Sa Li <sal...@gmail.com> wrote: > > > > > > > Guozhang > > > > > > > > Thank you very much for reply, here I print out the > > > > kafka-console-consumer.sh help, > > > > > > > > root@voluminous-mass:/srv/kafka# bin/kafka-console-consumer.sh > > > > Missing required argument "[zookeeper]" > > > > Option Description > > > > ------ ----------- > > > > --autocommit.interval.ms <Integer: ms> The time interval at which > to > > > save > > > > the > > > > current offset in ms > > (default: > > > > 60000) > > > > --blacklist <blacklist> Blacklist of topics to > exclude > > > from > > > > consumption. > > > > --consumer-timeout-ms <Integer: prop> consumer throws timeout > > exception > > > > after waiting this much of > > time > > > > without incoming messages > > > > (default: > > > > -1) > > > > --csv-reporter-enabled If set, the CSV metrics > > reporter > > > > will > > > > be enabled > > > > --fetch-size <Integer: size> The amount of data to fetch > in > > a > > > > single request.
