Method Details

afterTest

public void afterTest()

Description copied from class: TestCluster

This method should be executed during tear down, after each test (but after assertAfterTest)

Specified by:

afterTest in class TestCluster

client

public Client client()

Description copied from class: TestCluster

Returns a client connected to any node in the cluster

Specified by:

client in class TestCluster

size

public int size()

Description copied from class: TestCluster

Returns the number of nodes in the cluster.

Specified by:

size in class TestCluster

numDataNodes

public int numDataNodes()

Description copied from class: TestCluster

Returns the number of data nodes in the cluster.

Specified by:

numDataNodes in class TestCluster

numDataAndMasterNodes

public int numDataAndMasterNodes()

Description copied from class: TestCluster

Returns the number of data and master eligible nodes in the cluster.

Specified by:

numDataAndMasterNodes in class TestCluster

httpAddresses

public java.net.InetSocketAddress[] httpAddresses()

Description copied from class: TestCluster

Specified by:

httpAddresses in class TestCluster

close

public void close() throws java.io.IOException

Description copied from class: TestCluster

Closes the current cluster

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface java.io.Closeable

Specified by:

close in class TestCluster

Throws:

java.io.IOException

ensureEstimatedStats

public void ensureEstimatedStats()

Description copied from class: TestCluster

Ensures that any breaker statistics are reset to 0. The implementation is specific to the test cluster, because the act of checking some breaker stats can increase them.

Specified by:

ensureEstimatedStats in class TestCluster

Description copied from class: TestCluster

Returns this clusters NamedWriteableRegistry this is needed to deserialize binary content from this cluster that might include custom named writeables

Specified by:

getNamedWriteableRegistry in class TestCluster

getClusterName

public java.lang.String getClusterName()

Description copied from class: TestCluster

Returns the cluster name

Specified by:

getClusterName in class TestCluster
