Destination Kafka Cluster's Client Auth Only required if destination Kafka cluster requires client authentication. destination.ssl.client.auth false destination.ssl.client.auth false
Consumer Minimum Fetch Size The minimum amount of data the server should return for a fetch request. If insufficient data is available the request will wait for that much data to accumulate before answering the request. Setting this to something greater than 1 will cause the server to wait for larger amounts of data to accumulate which can improve server throughput a bit at the cost of some additional latency. fetch.min.bytes 1 B fetch.min.bytes false
Consumer Group ID Name of the consumer group used by MirrorMaker. When multiple role instances are configured with the same topics and same group ID, the role instances load-balance replication for the topics. When multiple role instances are configured with the same topics but different group ID, each role instance replicates all the events for those topics - this can be used to replicate the source cluster into multiple destination clusters. group.id cloudera_mirrormaker group.id false
Producer Linger Time The upper bound on the delay for batching. Once the producer gets a batch.size worth of records for a partition it will be sent immediately regardless of this setting.

Topic Auto Creation Enables auto creation of topics on the server. If this is set to true, then attempts to produce, consume, or fetch metadata for a non-existent topic automatically create the topic with the default replication factor and number of partitions. auto.create.topics.enable true auto.create.topics.enable false
Enable Automatic Leader Rebalancing If automatic leader rebalancing is enabled, the controller tries to balance leadership for partitions among the brokers by periodically returning leadership for each partition to the preferred replica, if it is available. auto.leader.rebalance.enable true auto.leader.rebalance.enable false
Enable Controlled Shutdown Enables controlled shutdown of the broker. If enabled, the broker moves all leaders on it to other brokers before shutting itself down. This reduces the unavailability window during shutdown. controlled.shutdown.enable true controlled.shutdown.enable false
Controlled Shutdown Maximum Attempts Number of unsuccessful controlled shutdown attempts before executing an unclean shutdown. For example, the default value of 3 means that the system will attempt a controlled shutdown 3 times before executing an unclean shutdown. controlled.shutdown.max.retries 3 controlled.shutdown.max.retries false
Default Replication Factor The default replication factor for automatically created topics. default.replication.factor 1 default.replication.factor false
Enable Delete Topic Enables topic deletion using admin tools. When delete topic is disabled, deleting topics through the admin tools has no effect. delete.topic.enable true delete.topic.enable false
List of Metric Reporters List of metric reporter class names. HTTP reporter is included by default. kafka.metrics.reporters nl.techop.kafka.KafkaHttpMetricsReporter kafka.metrics.reporters false
Enable Kerberos Authentication Enable Kerberos authentication for this KAFKA service. kerberos.auth.enable false kerberos.auth.enable false
Leader Imbalance Check Interval The frequency with which to check for leader imbalance. leader.imbalance.check.interval.seconds 5 minute(s) leader.imbalance.check.interval.seconds false
Leader Imbalance Allowed Per Broker The percentage of leader imbalance allowed per broker. The controller rebalances leadership if this ratio goes above the configured value per broker. leader.imbalance.per.broker.percentage 10 % leader.imbalance.per.broker.percentage false
Log Cleaner Deduplication Buffer Size The total memory used for log deduplication across all cleaner threads. This memory is statically allocated and will not cause GC problems. log.cleaner.dedupe.buffer.size 128 MiB log.cleaner.dedupe.buffer.size false
Log Compaction Delete Record Retention Time The amount of time to retain delete messages for log compacted topics. Once a consumer has seen an original message you need to ensure it also sees the delete message. If you removed the delete message too quickly, this might not happen. As a result there is a configurable delete retention time. log.cleaner.delete.retention.ms 7 day(s) log.cleaner.delete.retention.ms false
Enable Log Compaction Enables the log cleaner to compact topics with cleanup.policy=compact on this cluster. log.cleaner.enable true log.cleaner.enable false
Log Cleaner Clean Ratio Controls how frequently the log cleaner will attempt to clean the log. This ratio bounds the maximum space wasted in the log by duplicates. For example, at 0.5 at most 50% of the log could be duplicates. A higher ratio will mean fewer, more efficient cleanings but will mean more wasted space in the log. log.cleaner.min.cleanable.ratio 0.5 log.cleaner.min.cleanable.ratio false
Number of Log Cleaner Threads The number of background threads to use for log cleaning. log.cleaner.threads 1 log.cleaner.threads false
Log Flush Message Interval The number of messages written to a log partition before triggering an fsync on the log. Setting this lower syncs data to disk more often, but has a major impact on performance. Cloudera recommends use of replication for durability rather than depending on single-server fsync; however, this setting can be used to be extra certain. If used in conjunction with log.flush.interval.ms, the log is flushed when either criteria is met. log.flush.interval.messages log.flush.interval.messages false
Log Flush Time Interval The maximum time between fsync calls on the log. If used in conjuction with log.flush.interval.messages, the log is flushed when either criteria is met. log.flush.interval.ms log.flush.interval.ms false
Log Flush Scheduler Interval The frequency, in ms, with which the log flusher checks whether any log is eligible to be flushed to disk. log.flush.scheduler.interval.ms log.flush.scheduler.interval.ms false
Maximum Message Size The maximum size of a message that the server can receive. It is important that this property be in sync with the maximum fetch size the consumers use, or else an unruly producer could publish messages too large for consumers to consume. message.max.bytes 1000000 B message.max.bytes false
Minimum Number of Replicas in ISR The minimum number of replicas in the in-sync replica needed to satisfy a produce request where required.acks=-1 (that is, all). min.insync.replicas 1 min.insync.replicas false
Enable Kafka Monitoring (Note: Requires Kafka-1.3.0 parcel or higher) Enables Kafka monitoring. monitoring.enabled true monitoring.enabled false
Default Number of Partitions The default number of partitions for automatically created topics. num.partitions 1 num.partitions false
Number of Replica Fetchers Number of threads used to replicate messages from leaders. Increasing this value increases the degree of I/O parallelism in the follower broker. num.replica.fetchers 1 num.replica.fetchers false
Offset Commit Topic Number of Partitions The number of partitions for the offset commit topic. Since changing this after deployment is currently unsupported, Cloudera recommends using a higher setting for production (for example, 100-200). offsets.topic.num.partitions 50 offsets.topic.num.partitions false
Offset Commit Topic Replication Factor The replication factor for the offset commit topic. A higher setting is recommended in order to ensure higher availability (for example, 3 or 4) . If the offsets topic is created when there are fewer brokers than the replication factor, then the offsets topic is created with fewer replicas. offsets.topic.replication.factor 3 offsets.topic.replication.factor false
Default Consumer Quota Any consumer distinguished by clientId/consumer group will get throttled if it fetches more bytes than this value per-second. Only respected by Kafka 2.0 or later. quota.consumer.default quota.consumer.default false
Default Producer Quota Any producer distinguished by clientId will get throttled if it produces more bytes than this value per-second. Only respected by Kafka 2.0 or later. quota.producer.default quota.producer.default false
Replica Maximum Fetch Size The maximum number of bytes to fetch for each partition in fetch requests replicas send to the leader. This value should be larger than message.max.bytes. replica.fetch.max.bytes 1 MiB replica.fetch.max.bytes false
Allowed Replica Message Lag If a replica falls more than this number of messages behind the leader, the leader removes the follower from the ISR and treats it as dead. This property is deprecated in Kafka 1.4.0; higher versions use only replica.lag.time.max.ms. replica.lag.max.messages 4000 replica.lag.max.messages false
Allowed Replica Time Lag If a follower has not sent any fetch requests, nor has it consumed up to the leader's log end offset during this time, the leader removes the follower from the ISR set. replica.lag.time.max.ms 10 second(s) replica.lag.time.max.ms false
Enable Sentry Privileges Caching Enables Sentry privileges caching. Only applicable if authorization via Sentry is enabled. sentry.kafka.caching.enable true sentry.kafka.caching.enable false
Sentry Privileges Cache Refresh Interval The amount of time between updates of the Sentry privileges cache. Any change in role or privilege can take up to the specified time for changes to reflect in the cache. sentry.kafka.caching.ttl.ms 30 second(s) sentry.kafka.caching.ttl.ms false
Sentry Privileges Cache Maximum Update Failures If Sentry privileges cache fails to update for specified number of times, all authorization requests will be denied. sentry.kafka.caching.update.failures.count 3 sentry.kafka.caching.update.failures.count false

ZooKeeper Session Timeout If the server fails to send a heartbeat to ZooKeeper within this period of time, it is considered dead. If set too low, ZooKeeper might falsely consider a server dead; if set too high, ZooKeeper might take too long to recognize a dead server. zookeeper.session.timeout.ms 6 second(s) zookeeper.session.timeout.ms false
