分片修復（es 2.x 及之前）

curl -XPOST 'http://172.10.58.20:9200/_cluster/reroute' -d '{
     "commands": [
        {
            "allocate": {
                "index": "索引名字",
                "shard": 分片序號,
                "node": "節點標識",
                "allow_primary": true
          }
        }
    ]
  }'

curl -XPOST 'http://172.10.58.20:9200/_cluster/reroute' -d '{
     "commands": [
        {
            "allocate": {
                "index": "tweets",
                "shard": 0,
                "node": "aqNkSAuaQBiOWuLVWNOdtw",
                "allow_primary": true
