ExpectContinue property

[spyteric]

Env: hadoop 2.8.5
when use UploadFile() API,
hadoop will return "HTTP/1.1 100 Continue" before "HTTP/1.1 201 Created"
ExpectContinue need to be set true to get 201 otherwise EnsureSuccessStatusCode will throw an exception.

What is the error you are getting when using the library?

When I use UploadFile()
An exception throw shows "HttpRequestException: Response status code does not indicate success: 100 (Continue)."

After look into, server return 100 continue before 201.

HTTP/1.1 100 Continue

HTTP/1.1 201 Created
Location: hdfs://localhost:9000/tmp/1.txt
Content-Length: 0
Connection: close

Ah I see. I'm guessing this is without something like Apache Knox between your client and WebHDFS. I'm not sure if this is something where we can make sure we don't send the ExpectContinue header in the http client. I would hope the server doesn't just automatically return a "100 Continue" even if we don't ask for it. Can you put together a pull request to address the issue?
