Jeff Jirsa commented on CASSANDRA-9652:
---------------------------------------
[~carlo_4002] - this was fixed in CASSANDRA-13526 - upgrade to one of those
versions to fix it.
If you cant upgrade to those versions, you could (in theory) stop Cassandra and
manually remove the data directories for the keyspaces with replication factor
0, but please have a backup and know what you're doing before you try that (and
obviously you'd only stop one node at a time).
> Nodetool cleanup does not work for nodes taken out of replication
> -----------------------------------------------------------------
>
> Key: CASSANDRA-9652
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9652
> Project: Cassandra
> Issue Type: Bug
> Reporter: Erick Ramirez
> Priority: Minor
> Fix For: 3.11.x
>
>
> After taking a node (DC) out of replication, running a cleanup does not get
> rid of the data on the node. The SSTables remain on disk and no data is
> cleared out.
> The following entry is recorded in {{system.log}}:
> {noformat}
> INFO [CompactionExecutor:8] 2015-06-25 12:33:01,417 CompactionManager.java
> (line 527) Cleanup cannot run before a node has joined the ring
> {noformat}
> *STEPS TO REPRODUCE*
> # Build a (C* 2.0.10) cluster with multiple DCs.
> # Run {{cassandra-stress -n1}} to create schema.
> # Alter schema to replicate to all DCs.
> {noformat}
> cqlsh> ALTER KEYSPACE "Keyspace1" WITH replication = { 'class' :
> 'NetworkTopologyStrategy', 'DC1' : 2, 'DC2' : 2, 'DC3' : 1 } ;
> {noformat}
> # Run {{cassandra-stress -n100000}} to generate data.
> # Alter schema to stop replication to {{DC3}}.
> # On node in {{DC3}}, run {{nodetool cleanup}}.
> *WORKAROUND*
> # Stop Cassandra.
> # Manually delete the SSTables on disk.
> # Start Cassandra.
