  --------------------------------------------------
  <1> Node the shard is currently assigned to
  <2> The decision is "CURRENTLY_ASSIGNED" because the shard is currently assigned to this node
  
  You can also have Elasticsearch explain the allocation of the first unassigned
  shard it finds by sending an empty body, such as:
  
negative.code: --------------------------------------------------
  <1> Whether the shard is assigned or unassigned
  <2> Reason for the shard originally becoming unassigned
  <3> Configured delay before the shard can be allocated
  <4> Remaining delay before the shard can be allocated
  <5> User-added attributes the node has
  <6> The shard copy information for this node and error (if applicable)
  <7> Final decision and explanation of whether the shard can be allocated to this node
  <8> Weight for how much the allocator would like to allocate the shard to this node
  <9> List of node decisions factoring into final decision about the shard
  
  For a shard that is already assigned, the output looks similar to:
