Re: REST api: how to upload jar?

[Edward <eg...@hotmail.com>]

Has anyone successfully uploaded to the REST API using command line tools
(i.e. curl)? If so, please post an example.

Re: REST api: how to upload jar?

Let me try that again -- it didn't seem to render my commands correctly:

Thanks for the response, Shailesh. However, when I try with python, I get
the 
same error as when I attempted this with cURL: 

$ python uploadJar.py
java.io.FileNotFoundException:
/tmp/flink-web-4bed7801-fa5e-4e5e-abf1-3fa13ba1f528/438eaac1-7647-4716-8d8d-f95acd8129b2_/path/to/jar/file.jar
(No such file or directory)

That is, if I tell python (or cURL) that my jar file is at 
/path/to/jar/file.jar, the file path it uses on the server side includes 
that entire path in the target file name. And if I try the script with no
path (i.e. run the script 
in the folder where file.jar exists), it uploads an empty file named 
file.jar.  The endpoint at file/upload seems to be take the form-data 
element "jarfile" and use the fully qualified path when trying to save the 
jar file on the server side. 

Here is my equivalent attempt using cURL, which gives the same 
FileNoFoundException as above: 

curl 'http://localhost:8081/jars/upload' -H 'Content-Type:
multipart/form-data; boundary=----BoundaryXXXX' --data-binary
$'------BoundaryXXXX\r\nContent-Disposition: form-data; name="jarfile";
filename="/path/to/jar/file.jar"\r\nContent-Type:
application/java-archive\r\n\r\n\r\n------BoundaryXXXX--\r\n'

Thanks for the response, Shailesh. However, when I try with python, I get the
same error as when I attempted this with cURL:


That is, if I tell python (or cURL) that my jar file is at
/path/to/jar/file.jar, the file path it uses on the server side includes
that entire path. And if I try the script with no path (i.e. run the script
in the folder where file.jar exists), it uploads an empty file named
file.jar.  The endpoint at file/upload seems to be take the form-data
element "jarfile" and use the fully qualified path when trying to save the
jar file on the server side.

Here is my equivalent attempt using cURL, which gives the same
FileNoFoundException as above:

Re: REST api: how to upload jar?

[Shailesh Jain <sh...@stellapps.com>]

If you have python available, a simple script can help you there.

uploadJar.py:

> import requests # you might need to 'pip install requests' from command
> line
>
> uploadUrl = 'http://localhost:8081/jars/upload' # Replace localhost with
> your JobManager url
> jarName = '/path/to/jar/file.jar'
> files = {'file': (jarName, open(jarName, 'rb'),
> 'application/x-java-archive')}
> res = requests.post(uploadUrl, files=files)
> print res.json()
>

You can run this script by running "python uploadJar.py" from command line.

Hope it helps!
