-------------------------------------
Summary: Using an authenticated proxy server to access cloud storage from a cluster
Key: HADOOP-16288
URL: https://issues.apache.org/jira/browse/HADOOP-16288
Project: Hadoop Common
Issue Type: Improvement
Components: contrib/cloud
Reporter: Istvan Fajth
Given an environment which does not have direct access to the internet, but has to route all requests through a Proxy that requires authentication Hadoop filesystem commands can not go through.
My understanding of an [Official Java blog|https://blogs.oracle.com/wssfc/handling-proxy-server-authentication-requests-in-java], is that this requires a special Authenticator class to be used, which I do not see anywhere in the code, neither I could find any relevant parameter to set the proxy authentication credentials.
I tried to specify the proxy in a form of username:[password@host.fqdn|mailto:password@host.fqdn] and the port via java system properties, but that did not work either.
My use case is to connect to ADLS, but I have not seen relevant properties either for S3.
