如何从node.js删除hdfs文件

Question

I have the following file in hdfs

hdfs://localhost.localdomain:8020/user/cloudera/direccionbikes.out

I wrote a process in node.js and I need to delete this file. I use the api webhdfs.

I use createReadStream and createWriteStream in this program. But I don't know how to delete this file from node.js

Where can I read information about this question(webhdfs)

Answer 1

You can read about the APIs here - https://hadoop.apache.org/docs/r1.0.4/webhdfs.html

Submit a HTTP DELETE request .

curl -i -X DELETE "http://<host>:<port>/webhdfs/v1/<path>?op=DELETE
                              [&recursive=<true|false>]"

The client receives a response with a boolean JSON object:

HTTP/1.1 200 OK
Content-Type: application/json
Transfer-Encoding: chunked

{"boolean": true}
