/**
 *
 *对指定字段（脚本）的值按从小到大累计每个值对应的文档数的占比（占所有命中文档数的百分比），返回指定占比比例对应的值。
 * 默认返回[ 1, 5, 25, 50, 75, 95, 99 ]分位上的值。如下中间的结果，可以理解为：占比为50%的文档的age值 <= 31，
 * 或反过来：age<=31的文档数占总命中文档数的50%
 *  也可以自己指定分位值，如 10,50,90.
 * @param hostIp         ES集群的ip地址
 * @param port ES集群的端口号
 * @param clusterName  ES集群名称
 * @param indexName  ES集群的索引名称，可使用多个索引 indexName="test2,test1,test";
 * @param typeName 索引类型，可多个 typeName="doc,pdf,test";
 * @param aggFdName 字段名称
 * @param percentiles 自定义百分比分位数，比如10,50,90 之间以","分隔
 * @return
 * @throws TException
