Hi, I'm running a brand new Kafka cluster (version 0.9.0.0). During my tests I noticed this error at Consumer.partitionsFor during a full cluster restart. My DEV cluster is made of 4 brokers
Maybe I can workaround the error doing sanity checks on cluster /using my platform middleware tools) before instantiating the Consumer Should I file an issue on your JIRA ? Thanks This is my code: this.properties = new Properties(); properties.put("bootstrap.servers", "list of servers")); properties.put("acks", "all"); properties.put("retries", 0); properties.put("batch.size", 16384); properties.put("linger.ms", 1); properties.put("buffer.memory", 33554432); properties.put("group.id", "test"); properties.put("session.timeout.ms", "30000"); properties.put("key.deserializer", "org.apache.kafka.common.serialization.ByteArrayDeserializer"); properties.put("value.deserializer", "org.apache.kafka.common.serialization.ByteArrayDeserializer"); String topic = "xxx"; try (KafkaConsumer<byte[], byte[]> consumer = new KafkaConsumer<>(properties);) { List<PartitionInfo> partitions = consumer.partitionsFor(topic); .... } This is the error: java.lang.NullPointerException at org.apache.kafka.common.requests.MetadataResponse.<init>(MetadataResponse.java:130) at org.apache.kafka.clients.consumer.internals.Fetcher.getTopicMetadata(Fetcher.java:203) at org.apache.kafka.clients.consumer.KafkaConsumer.partitionsFor(KafkaConsumer.java:1143) at magnews.datastream.KafkaDataStreamConsumer.fetchNewData(KafkaDataStreamConsumer.java:44) Enrico Olivelli Software Development Manager @Diennea Tel.: (+39) 0546 066100 - Int. 925 Viale G.Marconi 30/14 - 48018 Faenza (RA) MagNews - E-mail Marketing Solutions http://www.magnews.it<http://www.magnews.it/> Diennea - Digital Marketing Solutions http://www.diennea.com<http://www.diennea.com/> ________________________________ Iscriviti alla nostra newsletter per rimanere aggiornato su digital ed email marketing! http://www.magnews.it/newsletter/ The information in this email is confidential and may be legally privileged.
