沙市，
我不知道是否粘贴了确切的命令行，但是如果粘贴了，可能需要在url周围添加引号，这样shell就不会解释&了。
在mapr 4.1上，这对我很有用：

[mapr@ip-172-16-2-19 ~]$ curl -k -u mapr:mapr 'https://ip-172-16-2-17:8443/rest/table/cf/list?path=/tmp/mytable&cfname=cf1' | jq .
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   345  100   345    0     0   1638      0 --:--:-- --:--:-- --:--:--  1642
{
  "timestamp": 1436384780597,
  "timeofday": "2015-07-08 07:46:20.597 GMT+0000",
  "status": "OK",
  "total": 1,
  "data": [
    {
      "cfname": "cf1",
      "maxversions": 1,
      "minversions": 0,
      "ttl": 2147483647,
      "inmemory": false,
      "compression": "lz4",
      "appendperm": "u:mapr",
      "compressionperm": "u:mapr",
      "memoryperm": "u:mapr",
      "readperm": "u:mapr",
      "versionperm": "u:mapr",
      "writeperm": "u:mapr"
    }
  ]
}

但是如果我像你的例子那样去掉引号，看看cfname参数看起来是如何被忽略的——这是因为当shell到达&时，它将命令放在后台，而cfname参数从来没有被服务器考虑过，因为它没有到达那里；所以maprcli列出了所有的cfs：

[mapr@ip-172-16-2-19 ~]$ curl -k -u mapr:mapr https://ip-172-16-2-17:8443/rest/table/cf/list?path=/tmp/mytable&cfname=cf1 | jq .
