--------------------------------------------
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.
