     I was trying to reproduce the same issue. But this code is working fine with brokers: ['localhost:9092']. There is no issue with this code you should check your Kafka server. There might be a possibility that your Kafka server is not configured properly.

     Try creating a topic from the terminal. You can find all the scripts inside your Kafka installation folder's bin directory.

     Run

     kafka-topics.sh --bootstrap-server localhost:9092 --create --topic test-topic --partitions 1 --replication-factor 1-

     Check if the topic is created successfully. If not there is a problem with your Kafka broker.

   • Kafka consumer group spending lot of time in rebalancing

     Top Answer

     Answered Oct 12, 2022 · 1 votes

     better to give the consumers an ID to reduce the rebalance time

     IDs don't affect consumer timeouts

     better to put them in separate consumer groups

     Depends on your use-case. Separate groups will track topic offsets uniquely. You can consume multiple topics per group, but if one topic has a lot more data than another, then you may not be processing as fast as you want. In that case, you can run multiple processes/treads per group and/or create new groups.

     I am modifying the parameter group.initial.rebalance.delay.ms in server.properties, are there rules to change this?

     Not that I know of. You'll need to restart the cluster to modify this, though.

     do you suggest that I change the heartbeat_interval_ms and the session_timeout_ms?

     Assuming your consumers are rebalancing from "doing too much", then yes.

     How?

     They are parameters to KafkaConsumer

     constructor...

     You may also want to try increasing max_poll_interval_ms

   • Kafka not a member of package error in spark app with kafka consumer

     Top Answer

     Answered Jul 15, 2021 · 0 votes

     kafka is not a member of package org.apache

     You should remove kafka-clients as a dependency since it conflicts with Spark's Kafka Integration

     object kafka010 is not a member of package org.apache.spark.streaming

     You've declared only spark-sql-kafka-0-10 (which depends on spark-core + spark-sql), and not spark-streaming-kafka (which is deprecated and where KafkaUtils

     comes from, and is not under a kafka010

     package)

     Refer docs for how to consume from Kafka with Spark Structured Streaming

   • Kafka multiple partitions of the same topic in the same broker

     Top Answer

     Answered Mar 11, 2022 · 6 votes

     Can Kafka have multiple partitions of the same topic in the same broker?

     Yes, it totally can. For example:

     ╰─$ ./bin/kafka-topics.sh --bootstrap-server localhost:9092 \ --create --topic rmoff-test \ --partitions 6 \ --replication-factor 1Created topic rmoff-test.╭─rmoff@asgard03 ~/Downloads/kafka_2.13-3.1.0╰─$ kcat -b localhost:9092 -LMetadata for all topics (from broker 1: localhost:9092/1): 1 brokers: broker 1 at localhost:9092 (controller) 1 topics: topic "rmoff-test" with 6 partitions: partition 0, leader 1, replicas: 1, isrs: 1 partition 1, leader 1, replicas: 1, isrs: 1 partition 2, leader 1, replicas: 1, isrs: 1 partition 3, leader 1, replicas: 1, isrs: 1 partition 4, leader 1, replicas: 1, isrs: 1 partition 5, leader 1, replicas: 1, isrs: 1

     It's possible you're mixing up the concept of partitions (used for strict ordering and high throughput) with that of partition replicas (used for availability/fault tolerance).

     You cannot have multiple replicas on one broker. If you try to create a topic with more replicas than available brokers it will fail:

     ╰─$ # There is one broker running ╰─$ kcat -b localhost:9092 -L | grep brokerMetadata for all topics (from broker 1: localhost:9092/1): 1 brokers: broker 1 at localhost:9092 (controller)╰─$ # Now try to create a topic with _one_ partition but _two_ replicas:╰─$ ./bin/kafka-topics.sh --bootstrap-server localhost:9092 \ --create --topic rmoff-test-2 \ --partitions 1 \ --replication-factor 2 Error while executing topic command : Unable to replicate the partition 2 time(s): The target replication factor of 2 cannot be reached because only 1 broker(s) are registered.[2022-03-11 09:51:33,721] ERROR org.apache.kafka.common.errors.InvalidReplicationFactorException: Unable to replicate the partition 2 time(s): The target replication factor of 2 cannot be reached because only 1 broker(s) are registered.
