Yiqun Lin commented on HDFS-10436:
----------------------------------
Hi, [~aw], the comments that I gave before seemed not correct. I am sorry for
that. The dfs.block.access.token.enable default on will let the method
{{createBlockTokenSecretManager}} return a new {{BlockTokenSecretManager}} and
then it means that BlockToken was enabled in {{BlockManager}}. It will change
the existed logic.
> dfs.block.access.token.enable should default on when security is !simple
