Kan Zhang commented on HADOOP-6367:
-----------------------------------
> Does this mean there is no security if I run the JobTracker and TaskTracker
> on a non-HDFS based file system?
That depends on whether that non-HDFS based file system enforces any access
control. It's unrelated to how HDFS does its access control. Access Token is a
feature of HDFS and currently I don't see how other file systems could make use
of it.
> Move Access Token implementation from Common to HDFS

> Access Token is HDFS specific and should be part of HDFS code base. Also,
> rename AccessToken to BlockAccessToken (and AccessKey to BlockAccessKey) to
> be more precise.
