如何使用ApacheDrill从amazons3查询数据？

使用spark将astextfile保存到s3之后，再像hadoop那样格式化。文件在bucket中的格式是这样的。

格式为年/月/日期/时间戳，数据为第0000部分，文件为json格式。
我配置钻并指向我的桶名

{
  "type": "file",
  "enabled": true,
  "connection": "s3://com.giaosudau.win-bid",
  "workspaces": {
    "root": {
      "location": "/",
      "writable": false,
      "defaultInputFormat": "json"
    },
    "tmp": {
      "location": "/tmp",
      "writable": true,
      "defaultInputFormat": null
    }
  },
  "formats": {
    "psv": {
      "type": "text",
      "extensions": [
        "tbl"
      ],
      "delimiter": "|"
    },
    "csv": {
      "type": "text",
      "extensions": [
        "csv"
      ],
      "delimiter": ","
    },
    "tsv": {
      "type": "text",
      "extensions": [
        "tsv"
      ],
      "delimiter": "\t"
    },
    "parquet": {
      "type": "parquet"
    },
    "json": {
      "type": "json"
    },
    "avro": {
      "type": "avro"
    }
  }
}

我选择的存储是确定的。但不知道如何选择和获取日期、小时或文件的数据。

我也尝试了一些方法，比如选择一个文件，但没有成功：

此处为文件示例

如何从中获取数据？

下面是一些使用数据和本地文件系统而不是s3的示例。我认为您的文件没有任何扩展名，但是如果不是这样，如果您的文件有.json扩展名，您可以这样查询它们（使用表别名t来解决歧义）：

use dfs.`root`;
+-------+---------------------------------------+
|  ok   |                summary                |
+-------+---------------------------------------+
| true  | Default schema changed to [dfs.root]  |
+-------+---------------------------------------+
1 row selected (0.079 seconds)
select t.auctionID from dfs.`/Users/khahn/drill/apache-drill-1.1.0/part-00000` t;
+------------+
| auctionId  |
+------------+
| xx         |
| 343        |
+------------+
2 rows selected (0.093 seconds)

如果您的文件没有扩展名，请修改存储插件配置，将defaultinputformat设置为“json”；否则，默认情况下，drill将假定文件为parquet格式。例如，我在根工作区中设置defaultinputformat：

{
  "type": "file",
  "enabled": true,
  "connection": "file:///",
  "workspaces": {
    "root": {
      "location": "/",
      "writable": false,
      "defaultInputFormat": "json"
    },
    "tmp": {
      "location": "/tmp",
      "writable": true,
      "defaultInputFormat": null
    }
  },
. . .

查询没有扩展名的文件时，需要指定在其中定义defaultinputformat的工作区，在本例中为root：

select t.auctionID from dfs.`root`.`/Users/khahn/drill/apache-drill-1.1.0/part-00000` t;
+------------+
| auctionId  |
+------------+
| xx         |
| 343        |
+------------+
2 rows selected (0.095 seconds)
