Jing Zhao updated HDFS-5085:
----------------------------
Attachment: HDFS-5085.005.patch
Update the patch to address Brandon's comments.
bq. 1. why NfsVerifier.readFlavorAndVerifier doesn't have AUTH_SYS check?
When the auth flavor is AUTH_SYS, the corresponding verifier is AUTH_NONE.
I.e., it is impossible to have a verifier with auth flavor AUTH_SYS.
> Refactor o.a.h.nfs to support different types of authentications
