MapR DB的MapR REST API看起来无法正常工作。我只是尝试列系列列表命令作为过滤器,但它没有给我正确的输出,但它完全适用于maprcli选项。这是我做的操作列表。
使用maprcli命令
maprcli table cf list -path / user / hbase / testShashi
readperm appendperm inmemory versionperm cfname writeperm compressperm memoryperm compression ttl maxversions minversions u:mapr u:mapr false u:mapr f1 u:mapr u:mapr u:mapr off 2147483647 1 0 u:mapr u:mapr false u:mapr f2 u:mapr u:mapr u:mapr off 2147483647 1 0
maprcli table cf list -path / user / hbase / testShashi -cfname f1
readperm appendperm inmemory versionperm cfname writeperm compressperm memoryperm compression ttl maxversions minversions u:mapr u:mapr false u:mapr f1 u:mapr u:mapr u:mapr off 2147483647 1 0
使用maprcli选项当我将cfname作为f1传递时,它只给我一条记录,但似乎不会发生REST API
使用REST API 在应用过滤器之前
curl -k -u mapr:mapr https://hostname:8443/rest/table/cf/list?path=/user/hbase/testShashi
curl -k -u mapr:mapr https://hostname:8443/rest/table/cf/list?path=/user/hbase/testShashi&cfname=f1
如果我在这里犯了任何错误,请告诉我。

沙市,
我不知道你是否粘贴了确切的命令行,但是如果你这样做了,你可能需要在网址周围添加引号以便&不是由shell解释的。
在MapR 4.1上,这对我有用:
[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,如果我在示例中删除引号,请查看cfname参数如何被忽略 - 这是因为当shell到达&时,它将命令放入后台,而cfname参数永远不会由服务器考虑,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 .
