Hi Knox-users, We have a use case as our secured cluster planning to block http url for webhdfs and only exposing https url as : https://cluster-mud-nn-2.ambari.com:50070/webhdfs/v1/?op=LISTSTATUS In that case while we access webhdfs via knox its throwing exception for SSL invalid certificate path. So do we need to import namenodes ssl signed certificate(.cer files) to knox host ../security/cacerts file right ? Or what we should do to make knox work to access https: webhdfs link.
