No live SolrServers available to handle this request

solr在启动的时候，发现日志如下所示：

2481 [Thread-1] INFO org.apache.solr.cloud.Overseer – Update state numShards=1 message={

"operation":"state",

"state":"down",

"base_url":"http://192.168.2.197:8081/search",

"core":"tika",

"roles":null,

"node_name":"192.168.2.197:8081_search",

"shard":"shard1",

"collection":"tika",

"numShards":"1",

"core_node_name":"192.168.2.197:8081_search_tika"}

state显示为down，所以在用solrj搜索的时候，提示没有可用的server来处理这个请求，查看apache-solr-ref-guide-4.7的"SolrCloud with Legacy Configuration Files"的这一节，发现有些配置文件没有配置，根据文档的描述，配置完成即可完成查询
