> Key: CURATOR-599
> URL: https://issues.apache.org/jira/browse/CURATOR-599
> Project: Apache Curator
> Issue Type: Improvement
> Components: Client
> Affects Versions: 5.1.0
> Reporter: Liran Mendelovich
> Priority: Major
> Time Spent: 3h 20m
> Remaining Estimate: 0h
>
> On some executions where ZooKeeper server is not available, Curator client
> got waiting and hanging indefinitely, with thread dump stack trace which can
> be seen
> below.
> As this is not reproduced consistently, it seems like a race condition from
> Curator/ZooKeeper client, since zookeeper.request.timeout cannot be
> configured in Curator client.
> As a work-around solution, initialization is executed in a separate thread in
> order to interrupt it if it hangs. This has been identified and handled here:
> [join_while_zookeeper_down_issue|https://github.com/CiscoSE/commons-cluster/blob/main/docs/join_while_zookeeper_down_issue.txt]
> The wanted solution is expose configuration to be able to configure
> zookeeper.request.timeout, then it should wait until the request timeout,
> which is treated at org.apache.zookeeper.ClientCnxn.submitRequest().
>
