Hey guys.. I have my my log level set to info, saying that I am not seeing much logs at all for kafka on startup i see detail about the serializer.class my producer uses but very little consumer related logs is there anything I should always see if my log config is correct for the info level
In relation to my settings for the number of streams here is my code. *Map<String, Integer> topicCountMap = new HashMap<>();* *//i've 20 threads for the topic for the 20 partitions with no replicas* *topicCountMap.put(topicConsumer.getTopic(), topicConsumer.getNumThreads());* *consumerConnector.createMessageStreams(topicCountMap);* Thanks Pablo On 24 Jul 2014 18:34, "Joe Stein" <joe.st...@stealth.ly> wrote: > What is the value for what you are setting for your number of streams when > calling createMessageStreamsByFilter or if using createMessageStreams for > the TopicCount ( topic -> numberOfStreams )? > > How are you threading the iterator on each stream? > > /******************************************* > Joe Stein > Founder, Principal Consultant > Big Data Open Source Security LLC > http://www.stealth.ly > Twitter: @allthingshadoop <http://www.twitter.com/allthingshadoop> > ********************************************/ > > > On Thu, Jul 24, 2014 at 1:05 PM, Pablo Picko <p...@pitchsider.com> wrote: > > > Guozhang > > > > I didn't no.
