Subject Re: Rest API cancel-with-savepoint: 404s when passing path as target-directory
Date Wed, 20 Sep 2017 08:55:13 GMT
Hi Emily,
I'm not familiar with the details of the REST API either but if this is a 
problem with the proxy, maybe it is already interpreting the encoded URL and 
passes it on un-encoded - have you tried encoding the path again? That is, 
encoding the percent-signs:

http://
{ip}:20888/proxy/application_1504649135200_0001/jobs/
1a0fd176ec8aabb9b8464fa481f755f0/cancel-with-savepoint/target-directory/
