这是我的hdfs版本：
名称节点'10.207.78.21:38234'
开始时间：2015年2月2日星期一19:16:43 cst
版本：1.0.4，r1393290
这是drill文件系统插件的配置：

{
  "type": "file",
  "enabled": true,
  "connection": "hdfs://10.207.78.21:38234",
  "config": null,
  "workspaces": {
    "root": {
    "location": "/",
    "writable": false,
    "defaultInputFormat": null
  },
  "tmp": {
    "location": "/tmp",
    "writable": true,
    "defaultInputFormat": null
  }
},
"formats": ...

这是我的测试数据：

bash-4.3$ ./hadoop fs -cat /test
{"key": "value"}

在嵌入模式下执行查询失败：

0: jdbc:drill:zk=local> SELECT * FROM rpmp.`/test` LIMIT 20;
