Greg Senia commented on HADOOP-9969: ------------------------------------ This also affects IBM JDK8... > TGT expiration doesn't trigger Kerberos relogin > ----------------------------------------------- > > Key: HADOOP-9969 > URL: https://issues.apache.org/jira/browse/HADOOP-9969 > Project: Hadoop Common > Issue Type: Bug > Components: ipc, security > Affects Versions: 2.1.0-beta > Environment: IBM JDK7 > Reporter: Yu Gao > Attachments: HADOOP-9969.patch, JobTracker.log > > > In HADOOP-9698 & HADOOP-9850, RPC client and Sasl client have been changed to > respect the auth method advertised from server, instead of blindly attempting > the configured one at client side. However, when TGT has expired, an > exception will be thrown from SaslRpcClient#createSaslClient(SaslAuth > authType), and at this time the authMethod still holds the initial value > which is SIMPLE and never has a chance to be updated with the expected one > requested by server, so kerberos relogin will not happen. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
