Abhijit Sarkar commented on CASSANDRA-15154:
--------------------------------------------
[~mshuler] I'm sure something in the logs can be dug out that'd tell an
experienced Cassandra user that the node is ready; however, the point of this
ticket is to make that very obvious. Even in the snippet you posted, "Starting
listening for CQL clients" isn't necessarily the same as "I'm ready". It can
easily be presumed that the node might have more to do after it had started
listening for CQL clients.
> Add console log to indicate the node is ready to accept requests

> 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}
