故障现象

GET /_cat/shards/7a_cool

7a_cool 5  r STARTED      4583018 759.4mb 10.2.4.21 pt01-pte-10-2-4-21
7a_cool 17 r UNASSIGNED                 10.2.4.22 pt01-pte-10-2-4-22  《==异常分片

解决办法：

    为分片指定运行主机：

for shard in $(curl -XGET http://10.2.4.37:9200/_cat/shards | grep UNASSIGNED | awk ‘{print $2}‘); do
    curl -XPOST ‘10.2.4.37:9200/_cluster/reroute‘ -H ‘Content-Type: application/json‘ -d ‘{
        "commands" : [ {
              "allocate" : {
                  "index" : "7a_cool", 
                  "shard" : $shard, 
                  "node" : "pt01-pte-10-2-4-37", 
                  "allow_primary" : true
              }
            }
        ]
    }‘
    sleep 5
done
