Re: Why there is no native shutdown command in cassandra
I just tested. It doesn't flush memtables like nodetool drain/flush command. Means it only does crash for the node, no graceful shutdown.

Yeah same as drain. Just exits at the end.

Re: Why there is no native shutdown command in cassandra
Thanks for information. Does stopdaemon also flush memtables and stop trift and CQL interface before shutting down the daemon ? does node also announce shutting down message in ring ?

Re: Why there is no native shutdown command in cassandra
Thanks, I am able to run the stopdaemon option in version 2.1. but it doesn't print anything in log for log level INFO about shutdown. In case of log level DEBUG , it prints shutdown information.

Re: Why there is no native shutdown command in cassandra
If you want to understand why, it's because C* was designed to be crash-only. https://www.usenix.org/conference/hotos-ix/crash-only-software Since this is great for the project but bad for operators experience we have later added this stopdaemon command.

Re: Why there is no native shutdown command in cassandra
As per Documentation(pasted as below), It does not stop Daemon . I tested also.I was looking for graceful shutdown for Cassandra Daemon.Description <https://docs.datastax.com/en/cassandra/2.1/cassandra/tools/toolsDrain.html?scroll=toolsDrain__description_unique_11> Flushes all memtables from the node to SSTables on disk. Cassandra stops listening for connections from the client and other nodes. You need to restart Cassandra after running nodetool drain. You typically use this command before upgrading a node to a new version of Cassandra. To simply flush memtables to disk, use nodetool flush.

Re: Why there is no native shutdown command in cassandra
In Cassandra 3.x, I think there is a "nodetool stopdaemon" command On Mon, Jun 13, 2016 at 6:28 PM, Anshu Vajpayee wrote: > Hi All > > Why we dont have native shutdown command in Cassandra ? > > Every software provides graceful shutdown command. > > > > Regards, > Anshu > > >
