Subject [jira] [Created] (CASSANDRA-11830) "nodetool flush" not flushing system keyspace
Date Wed, 18 May 2016 13:07:13 GMT
Dominik Keil created CASSANDRA-11830:

             Summary: "nodetool flush" not flushing system keyspace
                 Key: CASSANDRA-11830
             Project: Cassandra
          Issue Type: Bug
          Components: Tools
         Environment: Ubuntu 14.04, Oracle Java 8, Cassandra 2.2.6
            Reporter: Dominik Keil

I'm regularly splitting off maintenance systems from our QA cluster by adding a new node to
a new "datacenter", joining it, then stopping and removing it (adapting the schema before
and after accordingly).

In order to not mix up the systems I rename the cluster in the newly created maintenance system
by updating cluster_name in system.local

In the past, when running "nodetool flush" then restarting Cassandra, this worked as expected.

However, this time it did not. After restarting Cassandra the old cluster name was in place
every time. However, explicitly flushing the system keyspace using "nodetool flush system"
did work as expected.

Is this a bug or did the default behaviour of "nodetool flush" change at some point?
