> --------------------------------------------------------
>
> Key: CASSANDRA-12001
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12001
> Project: Cassandra
> Issue Type: Bug
> Components: Tool/nodetool
> Environment: Ubuntu: Linux 3.11.0-15-generic #25~precise1-Ubuntu SMP Thu Jan 30 17:39:31 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
> Cassandra Version :
> cassandra -v
> 2.1.2
> Reporter: Anshu Vajpayee
> Priority: Low
> Labels: lhf

> As per general opinion, nodetool stopdaemon should perform graceful shutdown rater than crash killing of cassandra daemon .
> It doesn't flush the memtables and also it doesn't stop the thrift and CQL connection interfaces before crashing/stopping the node. It directly calls SIGTERM on process as simple as kill -15/ctrl + c.

> 1. created a table like as below:
> cqlsh:test_ks> create table t2(id1 int, id2 text, primary key(id1));
> cqlsh:test_ks>
> cqlsh:test_ks> insert into t2(id1,id2) values (1,'a');
> cqlsh:test_ks> insert into t2(id1,id2) values (2,'a');
> cqlsh:test_ks> insert into t2(id1,id2) values (3,'a');
> cqlsh:test_ks> select * from t2;
> id1 | id2
> -----+-----
> 1 | a
> 2 | a
> 3 | a
> 2.Flush the memtable manually using nodetool flush
> student@cascor:~/node1/apache-cassandra-2.1.2/bin$ nodetool flush

> 4. Stopping the node using nodetool stopdaemon
> student@cascor:~$ nodetool stopdaemon
> Cassandra has shutdown.
> error: Connection refused
> -- StackTrace --
> java.net.ConnectException: Connection refused
> 5. No new version of SStables . Reason stopdaemon doesn't run nodetool flush/drain before actually stopping daemon.
