ela的UNASSIGNED索引修复

1、查找UNASSIGNED未分片的索引：

#curl -s "http://localhost:9200/_cat/shards" -u username:passwd | grep UNASSIGNED

2、找一台数据节点的唯一标识：172.16.16.44（43、45、46）都可以

#curl 'localhost:9200/_nodes/process?pretty' -u username:passwd

3、修复logstash-foo-2016.12.19索引，shard数表示UNASSIGNED中查到的未分片索引的标志

curl -XPOST 'localhost:9200/_cluster/reroute' -u username:passwd -d '{

         "commands" : [ {

               "allocate" : {

                  "index" : "logstash-foo-2016.12.19",

                   "shard" : 3,

                   "node" : "w_kwzooiQ329VTcDlKnp8Q",

                   "allow_primary" : true

              }

             }

         ]

     }'
