[jira] [Created] (HADOOP-18704) Support a "permissive" mode for secure clusters to allow "simple" auth clients

Ravi Kishore Valeti created HADOOP-18704:
--------------------------------------------

             Summary: Support a "permissive" mode for secure clusters to allow "simple" auth clients
                 Key: HADOOP-18704
                 URL: https://issues.apache.org/jira/browse/HADOOP-18704
             Project: Hadoop Common
          Issue Type: Improvement
          Components: ipc
    Affects Versions: 3.4.0, 2.10.3, 3.2.5, 3.3.6
            Reporter: Ravi Kishore Valeti


Similar to HBASE-14700, would like to add support for Secure Server to fallback to simple auth for non-secure clients.



Secure Hadoop to support a permissive mode to allow mixed secure and insecure clients. This allows clients to be incrementally migrated over to a secure configuration. To enable clients to continue to connect using SIMPLE authentication when the cluster is configured for security, set "hadoop.ipc.server.fallback-to-simple-auth-allowed" equal to "true" in hdfs-site.xml. NOTE: This setting should ONLY be used as a temporary measure while converting clients over to secure authentication. It MUST BE DISABLED for secure operation.
