Suresh Srinivas commented on HDFS-4278:
---------------------------------------
[~k.saruta] Instead of turning it on automatically, I agree that we should log
an error.
[~qwertymaniac] Can you please update the summary of the jira accordingly?
> The DFS_BLOCK_ACCESS_TOKEN_ENABLE config should be automatically turned on
> when security is enabled.

> 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.
