删除索引的Collection API(更多参见https://cwiki.apache.org/confluence/display/solr/Collections+API)

http://IP:PORT/solr/admin/collections?action=DELETEREPLICA&collection=IndexName&shard=shardX&replica=core_nodeX

shardX和core_nodeX来源于solr接口

http://IP:PORT/solr/zookeeper?detail=true&path=%2Fcollections%2FIndexName%2Fstate.json&_=1451891955901

把一个分片分为两个：

http://127.0.0.1:8983/solr/admin/collections?action=SPLITSHARD&collection={indexName}&shard=shard1

将一个分片删除：

http://127.0.0.1:8983/solr/admin/collections?action=DELETESHARD&collection={indexName}&shard=shard1_0
