public enum AllocationDecision extends java.lang.Enum<AllocationDecision> implements Writeable
Writeable.Reader<V>, Writeable.Writer<V>
Enum Constant | Description |
---|---|
ALLOCATION_DELAYED |
The allocation decision has been delayed waiting for a replica with a shard copy
that left the cluster to rejoin.
|
AWAITING_INFO |
Waiting on getting shard data from all nodes before making a decision
about where to allocate the shard.
|
NO |
The shard cannot be allocated, which can happen for any number of reasons,
including the allocation deciders gave a NO decision for allocating.
|
NO_ATTEMPT |
No attempt was made to allocate the shard
|
NO_VALID_SHARD_COPY |
The shard was denied allocation because there were no valid shard copies
found for it amongst the nodes in the cluster.
|
THROTTLED |
The allocation attempt was throttled for the shard.
|
WORSE_BALANCE |
The shard could not be rebalanced to another node despite rebalancing
being allowed, because moving the shard to the other node would not form
a better cluster balance.
|
YES |
The shard can be allocated to a node.
