> Key: HDFS-6666
> URL: https://issues.apache.org/jira/browse/HDFS-6666
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode, namenode, security
> Affects Versions: 3.0.0, 2.5.0
> Reporter: Chris Nauroth
> Assignee: Vijay Bhat
> Priority: Minor
> Attachments: HDFS-6666.001.patch, HDFS-6666.002.patch,
> HDFS-6666.003.patch
>
>
> Currently, if security is enabled by setting hadoop.security.authentication
> to kerberos, but HDFS block access tokens are disabled by setting
> dfs.block.access.token.enable to false (which is the default), then the
> NameNode logs an error and proceeds, and the DataNode proceeds without even
> logging an error. This jira proposes that this it's invalid to turn on
> security but not turn on block access tokens, and that it would be better to
> fail fast and abort the daemons during startup if this happens.
