Kan Zhang commented on HDFS-4056:
---------------------------------
bq. You need a technical reason for the -1. I agree with Daryn that the code
will be easier if we always have the secret manager. The overhead is minimal in
all cases, especially if you don't use tokens.
To start a daemon thread when you know you won't be using it (or worse, tokens
are issued but never used) is not only sloppy coding, but also confusing and
may lead to more bugs. In the parent JIRA, we have agreed on trying an approach
where SIMPLE is kept as is and SASL PLAIN is added for testing. See HADOOP-8779
for more discussions. If we go with that approach, there is no need for this
patch. And we should also revert HADOOP-8783 and HADOOP-8784.
