如何使用Apache Drill从AmazonS3查询数据？
使用Spark将asAsTextFile保存到S3然后格式化为Hadoop。 像这样的文件格式。
格式为YEAR / MONTH / DATE / TIMESTAMP 并且数据在part-0000文件中是json格式。
我配置钻取并指向我的存储桶名称
{
"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"
}
}
}
我选择存储是可以的。但不知道选择并获取日期或小时或文件的数据。
我也尝试过选择文件但不成功的事情：
此处提供文件示例

如何从中获取数据？
1 个答案:
答案 0 :(得分：2)
以下是使用您的数据和本地文件系统而不是s3的一些示例。我认为您的文件没有任何扩展名，但如果不是这样，如果您的文件具有.json扩展名，您可以像这样查询它们（使用表别名来解决歧义）：
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以将defaultInputFormat设置为“json”;否则，Drill假定文件默认为Parquet格式。例如，我在root工作区中设置了defaultInputFormat：
{
"type": "file",
"enabled": true,
"connection": "file:///",
"workspaces": {
"root": {
"location": "/",
"writable": false,
"defaultInputFormat": "json"
},
"tmp": {
"location": "/tmp",
"writable": true,
"defaultInputFormat": null
}
},
. . .
当您查询没有扩展名的文件时，您需要在此示例中指定您在其中定义defaultInputFormat，root的工作空间：
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)
请参阅有关处理类型差异的文档：https://drill.apache.org/docs/json-data-model/#handling-type-differences
