Subject [jira] [Commented] (CASSANDRA-11830) "nodetool flush" not flushing system keyspace
Date Tue, 03 Jan 2017 13:01:58 GMT


Paulo Motta commented on CASSANDRA-11830:

This seems like an unintended side-effect of skipping the system keyspaces just for the repair
command on CASSANDRA-5483 as noted by [], but it ended up skipping for
all nodetool commands that are executed without explicit keyspace set. So we can restore the
previous behavior for all commands, except repair.

> 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
> 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?
