Package org.elasticsearch.test.disruption

Class NetworkDisruption

java.lang.Object

org.elasticsearch.test.disruption.NetworkDisruption

All Implemented Interfaces:

ServiceDisruptionScheme

public class NetworkDisruption
extends java.lang.Object
implements ServiceDisruptionScheme

Network disruptions are modeled using two components: 1) the NetworkDisruption.DisruptedLinks represents the links in the network that are to be disrupted 2) the NetworkDisruption.NetworkLinkDisruptionType represents the failure mode that is to be applied to the links

static class	NetworkDisruption.IsolateAllNodes
static class	NetworkDisruption.NetworkDelay	Simulates slow or congested network.
static class	NetworkDisruption.NetworkLinkDisruptionType	Abstract class representing various types of network disruptions.
static class	NetworkDisruption.TwoPartitions	Creates two partitions with symmetric failures

Field Details

cluster

protected volatile InternalTestCluster cluster

activeDisruption

protected volatile boolean activeDisruption

DISCONNECT

public static final NetworkDisruption.NetworkLinkDisruptionType DISCONNECT

Simulates a network disconnect. Sending a request from source to target node throws a ConnectTransportException.

UNRESPONSIVE

public static final NetworkDisruption.NetworkLinkDisruptionType UNRESPONSIVE

Simulates an unresponsive target node by dropping requests sent from source to target node.

Constructor Details

NetworkDisruption

public NetworkDisruption(NetworkDisruption.DisruptedLinks disruptedLinks,
NetworkDisruption.NetworkLinkDisruptionType networkLinkDisruptionType)

Method Details

getDisruptedLinks

public NetworkDisruption.DisruptedLinks getDisruptedLinks()

getNetworkLinkDisruptionType

public NetworkDisruption.NetworkLinkDisruptionType getNetworkLinkDisruptionType()

applyToCluster

public void applyToCluster(InternalTestCluster cluster)

Specified by:

applyToCluster in interface ServiceDisruptionScheme

removeFromCluster

public void removeFromCluster(InternalTestCluster cluster)

Specified by:

removeFromCluster in interface ServiceDisruptionScheme

removeAndEnsureHealthy

public void removeAndEnsureHealthy(InternalTestCluster cluster)

Specified by:

removeAndEnsureHealthy in interface ServiceDisruptionScheme

ensureHealthy

public void ensureHealthy(InternalTestCluster cluster)

ensures the cluster is healthy after the disruption

ensureFullyConnectedCluster

public static void ensureFullyConnectedCluster(InternalTestCluster cluster)

Ensures that all nodes in the cluster are connected to each other. Some network disruptions may leave nodes that are not the master disconnected from each other. NodeConnectionsService will eventually reconnect but it's handy to be able to ensure this happens faster

ensureNodeCount

protected void ensureNodeCount(InternalTestCluster cluster)

applyToNode

public void applyToNode(java.lang.String node,
InternalTestCluster cluster)

Specified by:

applyToNode in interface ServiceDisruptionScheme

removeFromNode

public void removeFromNode(java.lang.String node1,
InternalTestCluster cluster)

Specified by:

removeFromNode in interface ServiceDisruptionScheme

testClusterClosed

public void testClusterClosed()

Specified by:

testClusterClosed in interface ServiceDisruptionScheme

startDisrupting

public void startDisrupting()

Specified by:

startDisrupting in interface ServiceDisruptionScheme

stopDisrupting

public void stopDisrupting()

Specified by:

stopDisrupting in interface ServiceDisruptionScheme

expectedTimeToHeal

public org.elasticsearch.common.unit.TimeValue expectedTimeToHeal()

Specified by:

expectedTimeToHeal in interface ServiceDisruptionScheme

toString

public java.lang.String toString()

Overrides:
