Constructor Detail

ClusterAllocationExplainRequest

public ClusterAllocationExplainRequest()

Create a new allocation explain request to explain any unassigned shard in the cluster.

ClusterAllocationExplainRequest

public ClusterAllocationExplainRequest(StreamInput in)
                                throws IOException

Throws:

IOException

Method Detail

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Specified by:

writeTo in interface Writeable

Overrides:

writeTo in class MasterNodeRequest<ClusterAllocationExplainRequest>

Throws:

IOException

validate

public ActionRequestValidationException validate()

Specified by:

validate in class ActionRequest

useAnyUnassignedShard

public boolean useAnyUnassignedShard()

Returns true iff the first unassigned shard is to be used

setIndex

public ClusterAllocationExplainRequest setIndex(String index)

Sets the index name of the shard to explain.

getIndex

@Nullable
public String getIndex()

Returns the index name of the shard to explain, or null to use any unassigned shard (see useAnyUnassignedShard()).

setShard

public ClusterAllocationExplainRequest setShard(Integer shard)

Sets the shard id of the shard to explain.

getShard

@Nullable
public Integer getShard()

Returns the shard id of the shard to explain, or null to use any unassigned shard (see useAnyUnassignedShard()).

setPrimary

public ClusterAllocationExplainRequest setPrimary(Boolean primary)

Sets whether to explain the allocation of the primary shard or a replica shard copy for the shard id (see getShard()).

isPrimary

@Nullable
public Boolean isPrimary()

Returns true if explaining the primary shard for the shard id (see getShard()), false if explaining a replica shard copy for the shard id, or null to use any unassigned shard (see useAnyUnassignedShard()).

setCurrentNode

public ClusterAllocationExplainRequest setCurrentNode(String currentNodeId)

Requests the explain API to explain an already assigned replica shard currently allocated to the given node.

getCurrentNode

@Nullable
public String getCurrentNode()

Returns the node holding the replica shard to be explained. Returns null if any replica shard can be explained.

includeYesDecisions

public void includeYesDecisions(boolean includeYesDecisions)

Set to true to include yes decisions for a particular node.

includeYesDecisions

public boolean includeYesDecisions()

Returns true if yes decisions should be included. Otherwise only "no" and "throttle" decisions are returned.

includeDiskInfo

public void includeDiskInfo(boolean includeDiskInfo)

Set to true to include information about the gathered disk information of nodes in the cluster.

includeDiskInfo

public boolean includeDiskInfo()

Returns true if information about disk usage and shard sizes should also be returned.

toString

public String toString()

Overrides:

toString in class Object

parse
