Applying custom Kudu configuration

If you applied any custom Kudu configurations in your CDH clusters, then you manually have to apply those configurations in your target Cloudera cluster.

If you have changed the value of tablet_history_max_age_sec and you plan to run incremental backups of Kudu on the target cluster, we recommend resetting tablet_history_max_age_sec to the default value of 1 week (see https://issues.apache.org/jira/browse/KUDU-2677).

Examples of commonly modified configuration flags:

rpc_max_message_size
tablet_transaction_memory
rpc_service_queue_length
raft_heartbeat_interval
heartbeat_interval_ms
memory_limit_hard_bytes
block_cache_capacity_mb

Once you manually applied custom configurations, restart the Kudu cluster.
