[jira] [Commented] (HDFS-4278) The DFS_BLOCK_ACCESS_TOKEN_ENABLE config should be automatically turned on when security is enabled.

    [ https://issues.apache.org/jira/browse/HDFS-4278?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13544062#comment-13544062 ] 

Eli Collins commented on HDFS-4278:
-----------------------------------

Or we should ERROR loudly if security is enabled and this config is not set if that's easier.

> When enabling security, one has to manually enable the config DFS_BLOCK_ACCESS_TOKEN_ENABLE (dfs.block.access.token.enable). Since these two are coupled, we could make it turn itself on automatically if we find security to be enabled.
