Method Detail

checkConsistency

public static void checkConsistency(SolrCloudManager solrCloudManager,
                                    AutoScalingConfig config)
                             throws Exception

Check consistency of data in a SolrCloudManager. This may be needed when constructing a simulated instance from potentially inconsistent data (eg. partial snapshots taken at different points in time).

Parameters:

solrCloudManager - source manager

config - optional AutoScalingConfig instance used to determine what node and replica metrics to check.

Throws:

Exception

calculateStats

public static Map<String,Object> calculateStats(SolrCloudManager cloudManager,
                                                      AutoScalingConfig config,
                                                      boolean verbose)
                                               throws Exception

Calculate statistics of node / collection and replica layouts for the provided SolrCloudManager.

Parameters:

cloudManager - manager

config - autoscaling config, or null if the one from the provided manager should be used

verbose - if true then add more details about replicas.

Returns:

a map containing detailed statistics

Throws:

Exception

v2AdminRequestToV1Params

public static ModifiableSolrParams v2AdminRequestToV1Params(V2Request req)

Convert a V2 CollectionAdminRequest to regular SolrParams

Parameters:

req - request

Returns:

request payload and parameters converted to V1 params

getRedactionContext

public static RedactionUtils.RedactionContext getRedactionContext(ClusterState clusterState)

Prepare collection and node / host names for redaction.

Parameters:

clusterState - cluster state
