Alejandro Abdelnur commented on HDFS-2316:
------------------------------------------
@Nicholas,
* gethomedir is required as you don't know where the FS impl creates the home
dir.
* The doAs parameter name was chosen to mimic the Java API, real.user is kind
of confusing, do you mean the proxy user or the doAs user. Plus when doing
Kerberos you don't use user.name. IMO doAs is a easier not to get confused.
* The GET_BLOCK_LOCATIONS private API, how are you differentiating private and
public APIs?
* Oozie could use delegation token or it could use doAs.
