Yongjun Zhang commented on HDFS-6776:
-------------------------------------
Thanks a lot [~tucu00]! I will address your comments in next rev.
I'm currently using message parsing to detect null token returned from server
due to lack of right exception. There is an advantage of this fix: we only need
to patch secure cluster side, and it will work. To introduce a new exception
means compatibility issue, if we decide to do so, we can file a follow-up jira
for release 3.0? Thanks.
