Summary: Handle SessionTimeoutException in Java client Key: ZOOKEEPER-4692 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4692 Project: ZooKeeper Issue Type: Bug Components: java client Affects Versions: 3.8.1 Reporter: Giorgos Georgiou The Java client sets a read timeout equal to 2/3 of the session timeout and throws a SessionTimeoutException when this is hit. [https://github.com/apache/zookeeper/blob/89c1831f84891f425f1fa9224210587124f1c1ec/zookeeper-server/src/main/java/org/apache/zookeeper/ClientCnxn.java#L1236-L1243] However, the effect of that exception is not treated the same was as a SessionExpiredException which is propagated to the user and instead is treated as a disconnect event instead. This doesn't play very well with Curator which manages its own exception expiry client side and starts its countdown on disconnect events, meaning that it will consider the session lost a whole 2/3 of the session timeout after it actually expired. Should the SessionTimeoutException also be propagated to the users for handling and potentially considering the session lost from their end? -- This message was sent by Atlassian Jira (v8.20.10#820010)
