awaitNoPendingTasks

public static void awaitNoPendingTasks(ClusterService clusterService)

addTemporaryStateListener

public static SubscribableListener<Void> addTemporaryStateListener(ClusterService clusterService,
 Predicate<ClusterState> predicate)

Creates a ClusterStateListener which subscribes to the given ClusterService and waits for it to apply a cluster state that satisfies predicate, at which point it unsubscribes itself.

Returns:

A SubscribableListener which is completed when the first cluster state matching predicate is applied by the given clusterService. If the current cluster state already matches predicate then the returned listener is already complete. If no matching cluster state is seen within ESTestCase.SAFE_AWAIT_TIMEOUT then the listener is completed exceptionally on the scheduler thread that belongs to clusterService.

addTemporaryStateListener

public static SubscribableListener<Void> addTemporaryStateListener(ClusterService clusterService,
 Predicate<ClusterState> predicate,
 org.elasticsearch.core.TimeValue timeout)

Creates a ClusterStateListener which subscribes to the given ClusterService and waits for it to apply a cluster state that satisfies predicate, at which point it unsubscribes itself.

Returns:

A SubscribableListener which is completed when the first cluster state matching predicate is applied by the given clusterService. If the current cluster state already matches predicate then the returned listener is already complete. If no matching cluster state is seen within the provided timeout then the listener is completed exceptionally on the scheduler thread that belongs to clusterService.

addTemporaryStateListener

public static SubscribableListener<Void> addTemporaryStateListener(Predicate<ClusterState> predicate)

Creates a ClusterStateListener which subscribes to the ClusterService of one of the nodes in the ESIntegTestCase.internalCluster(). When the chosen ClusterService applies a state that satisfies predicate the listener unsubscribes itself.

Returns:

A SubscribableListener which is completed when the first cluster state matching predicate is applied by the ClusterService belonging to one of the nodes in the ESIntegTestCase.internalCluster(). If the current cluster state already matches predicate then the returned listener is already complete. If no matching cluster state is seen within ESTestCase.SAFE_AWAIT_TIMEOUT then the listener is completed exceptionally on the scheduler thread that belongs to the chosen node's ClusterService.

addMasterTemporaryStateListener

public static SubscribableListener<Void> addMasterTemporaryStateListener(Predicate<ClusterState> predicate)

Creates a ClusterStateListener which subscribes to the ClusterService of the current elected master node in the ESIntegTestCase.internalCluster(). When this node's ClusterService applies a state that satisfies predicate the listener unsubscribes itself.

Returns:

A SubscribableListener which is completed when the first cluster state matching predicate is applied by the ClusterService belonging to the node that was the elected master node in the ESIntegTestCase.internalCluster() when this method was first called. If the current cluster state already matches predicate then the returned listener is already complete. If no matching cluster state is seen within ESTestCase.SAFE_AWAIT_TIMEOUT then the listener is completed exceptionally on the scheduler thread that belongs to the elected master node's ClusterService.
