Does someone know if logstash plugin support authentication with Knox ? I'm running logstash-6.3.1 (not ELK distribution) locally on windows trying to push data to hdfs (on remote server) with webhdfs and authenticate with Knox, but logstash fails to start - unable to connect. Logstash config contains: Output ( webhdfs(host=\>"[knoxcluster.com:123/.../webhdfs/v1](http://knoxcluster.com:123/.../webhdfs/v1)" ... At the same time the curl request on windows gitbash to remote server works fine curl -iku user:password -X GET 'https:knoxcluster.com:123/.../webhdfs/v1/?op=gethomedirectory' I looked at the source [https://github.com/logstash-plugins/logstash-output-hdfs/blob/master/lib/logstash/outputs/webhdfs.rb](https://github.com/logstash-plugins/logstash-output-hdfs/blob/master/lib/logstash/outputs/webhdfs.rb) and it seems that the code is not designed to handle the Knox authentication. Any help will be appreciated ---
