Haohui Mai created HADOOP-11726: ----------------------------------- Summary: Allow applications to access both secure and insecure clusters at the same time Key: HADOOP-11726 URL: https://issues.apache.org/jira/browse/HADOOP-11726 Project: Hadoop Common Issue Type: Bug Reporter: Haohui Mai
Today there are multiple integration issues when an application (particularly, distcp) access both secure and insecure clusters (e.g., HDFS-6776 / HDFS-7036) There are four use cases in this scenario: * Secure <-> Secure. Works. * Insecure <-> Insecure. Works. * Accessing secure clusters from insecure client. Will not work as expected. The insecure client won't be able to be authenticated with the secure client, otherwise it is a security vulnerability. * Accessing insecure clusters from secure client. Currently it will not work as the secure client won't be able to obtain a delegation token from the insecure cluster. This jira proposes to fix the last use case. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
