Method Details

awaitReassignmentOfKafkaInternalTopicsIfNecessary

public static void awaitReassignmentOfKafkaInternalTopicsIfNecessary(Map<String,Object> connectionConfig,
 int fromNodeId,
 int toNodeId,
 int timeout,
 TimeUnit timeUnit)

Reassign all kafka internal topic partitions that exist have a replica on fromNodeId and don't have at least one replica elsewhere in the cluster.

Parameters:

connectionConfig - the connection config

fromNodeId - nodeId being evacuated

toNodeId - replacement nodeId

timeout - the timeout

timeUnit - the time unit

awaitExpectedBrokerCountInClusterViaTopic

public static void awaitExpectedBrokerCountInClusterViaTopic(Map<String,Object> connectionConfig,
 int timeout,
 TimeUnit timeUnit,
 Integer expectedBrokerCount)

Await expected broker count in cluster. Verifies that all expected brokers are present in the cluster.

To Verify that all the expected brokers are in the cluster we create a topic with a replication factor = to the expected number of brokers. We then poll describeTopics until

Parameters:

connectionConfig - the connection config

timeout - the timeout

timeUnit - the time unit

expectedBrokerCount - the expected broker count

awaitCondition

public static org.awaitility.core.ConditionFactory awaitCondition(int timeout,
 TimeUnit timeUnit)

Factory for Awaitility.await() preconfigured with defaults.

Parameters:

timeout - at most timeout

timeUnit - at most TimeUnit

Returns:

preconfigured factory
