[jira] [Commented] (CASSANDRA-15154) Add console log to indicate
the node is ready to accept requests
[ https://issues.apache.org/jira/browse/CASSANDRA-15154?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16861732#comment-16861732 ]
Michael Shuler commented on CASSANDRA-15154:
--------------------------------------------
Close - not a bug?
Generally, one or two lines before the ones you listed is the line you're looking for. The "listening for CQL clients" line is the equivalent of "I've started and I'm ready for connections":

Longer sample on fresh start including lines you listed:

> Key: CASSANDRA-15154
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15154
> Project: Cassandra
> Issue Type: Improvement
> Components: Cluster/Membership, Local/Startup and Shutdown, Observability/Logging
> Reporter: Abhijit Sarkar
> Priority: Normal
>
> Depending on whether a cluster is initialized the first time, or a node is restarted, the last message on the console varies. In either case, there's no indication that the cluster/node is ready to accept requests.
> For example, when I create a new Cassandra Docker container locally:
> {code}
> $ docker run --name cas -p 9042:9042 -p 9091:9091 -e CASSANDRA_DC=dev cassandra
> ...
> INFO [OptionalTasks:1] 2019-06-11 23:31:35,527 CassandraRoleManager.java:356 - Created default superuser role 'cassandra'
> {code}
> After shutting it down (CTRL + C), and restarting:
> {code}
> $ docker start cas
> ...
> INFO [main] 2019-06-11 23:32:57,980 CassandraDaemon.java:556 - Not starting RPC server as requested. Use JMX (StorageService->startRPCServer()) or nodetool (enablethrift) to start it
> {code}
> In either of the above cases, how is a regular user, whose full time job is not working with Cassandra, expected to know whether the server is ready? We have a new member in the team who previously was an iOS developer. He left the server running overnight, assuming the node hadn't finished initialization; the next morning, the last message was still "Created default superuser role 'cassandra'".
> Please add a simple log statement with basic information like node IPs in the cluster indicating the node is ready. For example, this is what Spring Boot does:
> {code}
> 2019-06-11 16:37:28.295 INFO [my-app,,,] 17392 --- [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat started on port(s): 11900 (http) with context path ''
> 2019-06-11 16:37:28.299 INFO [my-app,,,] 17392 --- [ main] mypackage.MyApp : Started MyApp in 5.279 seconds (JVM running for 5.916)
> {code}
