Daryn Sharp updated HADOOP-9852: -------------------------------- Attachment: HADOOP-9852.patch # Track principal and keytab in the login conf # Add login conf to the subject # Reuse the subject's login conf for relogin # Remove one more synch on the class... > UGI login user keytab and principal should not be static > -------------------------------------------------------- > > Key: HADOOP-9852 > URL: https://issues.apache.org/jira/browse/HADOOP-9852 > Project: Hadoop Common > Issue Type: Sub-task > Components: security > Affects Versions: 2.0.0-alpha, 3.0.0 > Reporter: Daryn Sharp > Assignee: Daryn Sharp > Attachments: HADOOP-9852.patch > > > The static keytab and principal for the login user is problematic. The login > conf explicitly references these statics. As a result, > loginUserFromKeytabAndReturnUGI is unnecessarily synch'ed on the class to > swap out the login user's keytab and principal, login, then restore the > keytab/principal. This method's synch blocks further de-synching of other > methods. -- This message is automatically generated by JIRA.
