---------------------------
Attachment: HADOOP-9969.patch
> 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
> Attachments: HADOOP-9969.patch
>
>
> 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.
