Wei-Chiu Chuang commented on HADOOP-16881:
------------------------------------------
Thanks for the patch, LGTM +1
Note to myself:
the connection leak inside the delegation token authenticator doesn't look that
critical, compared to the Kerberos authenticator, because the leak will only
happen for getDelegationToken(), renewDelegationToken(), cancelDelegationToken.
Unrelated to the patch itself, someone should review the ATS code to understand
why the connection is not reused. Without using delegation tokens, a typical
workflow is the kerberos authenticator acquires credentials, and then another
connection to send requests. That subsequent request connection should be
reused.
