Fix problems with Kerberos TGT renewal
--------------------------------------
Key: ZOOKEEPER-1181
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1181
Project: ZooKeeper
Issue Type: Bug
Components: java client, server
Affects Versions: 3.4.0
Reporter: Eugene Koontz
Assignee: Eugene Koontz
Fix For: 3.4.0
Currently, in Zookeeper trunk, there are two problems with Kerberos TGT renewal:
1. TGTs obtained from a keytab are not refreshed periodically. They should be,
just as those from ticket cache are refreshed.
2. Ticket renewal should be retried if it fails. Ticket renewal might fail if
two or more separate processes (different JVMs) running as the same user try to
renew Kerberos credentials at the same time.
