Method Detail

waitForAllActiveAndLiveReplicas

public static boolean waitForAllActiveAndLiveReplicas(org.apache.solr.common.cloud.ZkStateReader zkStateReader,
                                                      int timeoutInMs)

Wait to see *all* cores live and active.

Parameters:

zkStateReader - to use for ClusterState

timeoutInMs - how long to wait before giving up

Returns:

false if timed out

waitForAllActiveAndLiveReplicas

public static boolean waitForAllActiveAndLiveReplicas(org.apache.solr.common.cloud.ZkStateReader zkStateReader,
                                                      String collection,
                                                      int timeoutInMs)

Wait to see *all* cores live and active.

Parameters:

zkStateReader - to use for ClusterState

collection - to look at

timeoutInMs - how long to wait before giving up

Returns:

false if timed out

waitForAllReplicasNotLive

public static boolean waitForAllReplicasNotLive(org.apache.solr.common.cloud.ZkStateReader zkStateReader,
                                                int timeoutInMs)

waitForAllReplicasNotLive

public static boolean waitForAllReplicasNotLive(org.apache.solr.common.cloud.ZkStateReader zkStateReader,
                                                String collection,
                                                int timeoutInMs)

getLiveAndActiveReplicaCount

public static int getLiveAndActiveReplicaCount(org.apache.solr.common.cloud.ZkStateReader zkStateReader,
                                               String collection)

replicasOfActiveSlicesStream

public static Stream<org.apache.solr.common.cloud.Replica> replicasOfActiveSlicesStream(org.apache.solr.common.cloud.DocCollection collectionState)

waitForLiveAndActiveReplicaCount

public static boolean waitForLiveAndActiveReplicaCount(org.apache.solr.common.cloud.ZkStateReader zkStateReader,
                                                       String collection,
                                                       int replicaCount,
                                                       int timeoutInMs)

waitFor

public static boolean waitFor(org.apache.solr.common.cloud.ZkStateReader zkStateReader,
                              String collection,
                              long timeout,

                              org.apache.solr.common.cloud.CollectionStatePredicate predicate)

Calls ZkStateReader.waitForState(String, long, TimeUnit, CollectionStatePredicate) but has an alternative implementation if collection is null, in which the predicate must match *all* collections. Returns whether the predicate matches or not in the allotted time; does *NOT* throw TimeoutException.

toDebugAllStatesString

public static String toDebugAllStatesString(org.apache.solr.common.cloud.ClusterState clusterState)

Produces a String of all the collection states for debugging. ZK may be consulted.
