rest - MapR-Rest API列表命令未提供正确的输出

Question

用于MapR DB的MapR REST API似乎无法正常工作。我只是尝试将列系列的列表命令用作过滤器，但它没有给我适当的输出，但它与maprcli选项完美配合。这是我所做的操作列表。

使用maprcli命令

maprcli表cf列表-path / user / hbase / testShashi

readperm附录perm内存版本perm cfname writeperm压缩perm内存perm压缩ttl maxversions minversions
u:mapr u:mapr否u:mapr f1 u:mapr u:mapr u:mapr off 2147483647 1 0
u:mapr u:mapr否u:mapr f2 u:mapr u:mapr u:mapr off 2147483647 1 0

maprcli表cf列表-path / user / hbase / testShashi -cfname f1

readperm附录perm内存版本perm cfname writeperm压缩perm内存perm压缩ttl maxversions minversions
u:mapr u:mapr否u:mapr f1 u:mapr u:mapr u:mapr off 2147483647 1 0

当我将cfname传递为f1时，使用maprcli选项，它仅给我单条记录，但使用REST API似乎没有发生

使用REST API
应用过滤器之前

curl -k -u mapr:mapr https://hostname:8443/rest/table/cf/list?path=/user/hbase/testShashi

cft名称为的

curl -k -u mapr:mapr https://hostname:8443/rest/table/cf/list?path=/user/hbase/testShashi&cfname=f1

让我知道我是否在这里犯任何错误。

我不知道您是否粘贴了确切的命令行，但是如果这样做了，则可能需要在URL周围添加引号，以使＆不会被 shell 程序解释。

在MapR 4.1上，这对我有效:

[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，如果我像您的示例中那样删除引号，请参阅cfname参数似乎是如何被忽略的-这是因为，当shell到达＆时，它将命令置于后台，并且服务器永远不会考虑cfname参数。因为它没有到达那里；因此maprcli列出了所有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 .
