------------------------------------------
Summary: ZooKeeper client enters into infinite AuthFailedException
exception cycle if its unable to recreate Kerberos ticket
Key: ZOOKEEPER-2323
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2323
Project: ZooKeeper
Issue Type: Bug
Components: java client
Reporter: Arshad Mohammad
Assignee: Arshad Mohammad
Fix For: 3.5.2
ZooKeeper client enters into infinite AuthFailedException cycle. For every
operation its throws AuthFailedException
Here is the create operation exception
{code}
org.apache.zookeeper.KeeperException$AuthFailedException: KeeperErrorCode =
AuthFailed for /continuousRunningZKClient
at org.apache.zookeeper.KeeperException.create(KeeperException.java:127)
at org.apache.zookeeper.KeeperException.create(KeeperException.java:51)
at org.apache.zookeeper.ZooKeeper.getData(ZooKeeper.java:1753)
{code}
This can be reproduced easily with the following steps:
# Reduce the ZooKeeper client principal max life for example set 2 min. use
command {color:blue} modprinc -maxlife 2min zkcli {color} in kadmin. (This is
done to reduce the issue reproduce time)
# Connect Client to ZooKeeper quorum,let it gets connected and some operations
are done successfully
# Disconnect the Client's network, by pulling out the Ethernet cable or by any
way. Now the Client is in disconnected state, no operation is expected,Client
tries to reconnect to different-different servers in the ZooKeeper quorum.
# After two minutes Client tries to get new Keberos ticket and it fails.
# Connect the Client to network. Client comes in connected state but
AuthFailedException for every operation.
