Summary: Kerberos keytabs not working for YARN deployment mode Key: FLINK-5580 URL: https://issues.apache.org/jira/browse/FLINK-5580 Project: Flink Issue Type: Bug Components: Security, YARN Reporter: Tzu-Li (Gordon) Tai Assignee: Tzu-Li (Gordon) Tai Priority: Critical Fix For: 1.2.0 Setup: Kerberos security using keytabs, Flink on YARN deployment (in standalone, it works fine without problems). I’m getting these error messages in the YARN node managers, causing the TaskManager containers to fail to start properly: {{org.apache.hadoop.security.UserGroupInformation: PriviledgedActionException as:tzulitai (auth:SIMPLE) cause:org.apache.hadoop.security.AccessControlException: Client cannot authenticate via:[TOKEN, KERBEROS]}} The security configuration for Hadoop has been set to "kerberos", to the "auto: SIMPLE" seems very strange. It also seems as if credential tokens has not been properly set for the `ContainerLaunchContext`s, which may be an issue causing this. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
