tasanuma commented on issue #1414: HDFS-14835. RBF: Secured Router should not run when it can't initialize DelegationTokenSecretManager URL: https://github.com/apache/hadoop/pull/1414#issuecomment-529730451 @goiri @chittshota Thanks for your reviews. In this PR, the error occurs only when the authentication method is kerberos. Given that YARN uses delegation tokens to communicate with HDFS when the authentication method is kerberos, I think kerberized router should fail to start if secret manager is broken.
