Hi, developers Sorry to interrupt and wish you have a good day. As we know, impersonation is quite a common operation in gateway access model. And I've found that the SPNEGO filter doesn't support impersonation aka "doAs" operation, and it causes limitation of accessing pages both in HDFS and YARN when users set the auth filter as SPNEGO filter. Here is the JIRA(HADOOP-13119 <https://issues.apache.org/jira/browse/HADOOP-13119>) to track all the discussion.
I'd like to bring it to the community and get your thoughts since this JIRA has been suspended for a while. If you have any suggestion about this JIRA, please let me know, thanks in advance.
