Enum UnassignedInfo.AllocationStatus

java.lang.Object

java.lang.Enum<UnassignedInfo.AllocationStatus>

org.elasticsearch.cluster.routing.UnassignedInfo.AllocationStatus

All Implemented Interfaces:

Serializable, Comparable<UnassignedInfo.AllocationStatus>, Writeable

Enclosing class:

UnassignedInfo

public static enum UnassignedInfo.AllocationStatus
extends Enum<UnassignedInfo.AllocationStatus>
implements Writeable

Captures the status of an unsuccessful allocation attempt for the shard, causing it to remain in the unassigned state. Note, ordering of the enum is important, make sure to add new values at the end and handle version serialization properly.

Enum Constant Summary

Enum Constants

Enum Constant	Description
DECIDERS_NO	The shard was denied allocation to a node because the allocation deciders all returned a NO decision
DECIDERS_THROTTLED	The allocation attempt was throttled on the shard by the allocation deciders
DELAYED_ALLOCATION	Allocation decision has been delayed
FETCHING_SHARD_DATA	Waiting on getting shard data from all nodes before making a decision about where to allocate the shard
NO_ATTEMPT	No allocation attempt has been made yet
NO_VALID_SHARD_COPY	The shard was denied allocation to a node because there were no valid shard copies found for it; this can happen on node restart with gateway allocation

Enum Constant Detail

DECIDERS_NO

public static final UnassignedInfo.AllocationStatus DECIDERS_NO

The shard was denied allocation to a node because the allocation deciders all returned a NO decision

NO_VALID_SHARD_COPY

public static final UnassignedInfo.AllocationStatus NO_VALID_SHARD_COPY

The shard was denied allocation to a node because there were no valid shard copies found for it; this can happen on node restart with gateway allocation

DECIDERS_THROTTLED

public static final UnassignedInfo.AllocationStatus DECIDERS_THROTTLED

The allocation attempt was throttled on the shard by the allocation deciders

FETCHING_SHARD_DATA

public static final UnassignedInfo.AllocationStatus FETCHING_SHARD_DATA

Waiting on getting shard data from all nodes before making a decision about where to allocate the shard

DELAYED_ALLOCATION

public static final UnassignedInfo.AllocationStatus DELAYED_ALLOCATION

Allocation decision has been delayed

NO_ATTEMPT

public static final UnassignedInfo.AllocationStatus NO_ATTEMPT

No allocation attempt has been made yet

Method Detail

values

public static UnassignedInfo.AllocationStatus[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (UnassignedInfo.AllocationStatus c : UnassignedInfo.AllocationStatus.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static UnassignedInfo.AllocationStatus valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Specified by:

writeTo in interface Writeable

Throws:

IOException

readFrom

public static UnassignedInfo.AllocationStatus readFrom(StreamInput in)
                                                throws IOException

Throws:

IOException

fromDecision

public static UnassignedInfo.AllocationStatus fromDecision(Decision.Type decision)

value

public String value()
