Yu Gao created HADOOP-9969:
------------------------------
Summary: 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
Reporter: Yu Gao
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.
