Hi,
We are using Kafka 0.9.0.2, and by default log cleaner is not enabled. When we enable the log cleaner, internal topic “__consumer_offsets” (around 1TB in size)starts compaction, and during compaction we are unable to consume/produce messages. Also, consumer groups failed in leader election. Partitions – 6 Kafka nodes – 3 Zookeeper – 3 Replication factor – 3 - Prasanna
