---------------------------------------
Summary: Improve logging when the connection to a remote server is
closed
Key: ZOOKEEPER-4791
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4791
Project: ZooKeeper
Issue Type: New Feature
Components: server
Affects Versions: 3.9.1
Reporter: Sönke Liebau
When a server closes the connection to a remote server, the logging around why
the connection is being closed could be improved a bit.
https://github.com/apache/zookeeper/blob/1cc1eb6a2be7323a5c326652d59a070473bb8779/zookeeper-server/src/main/java/org/apache/zookeeper/server/NettyServerCnxn.java#L524
{code:java}
ZooKeeperServer zks = this.zkServer;
if (zks == null || !zks.isRunning()) {
LOG.info("Closing connection to {} because the
server is not ready",
getRemoteSocketAddress());
close(DisconnectReason.IO_EXCEPTION);
return;
}
{code}
It would be helpful to log what zkServer is, because it can have multiple
states that would trigger this shutdown.
