[jira] [Commented] (CASSANDRA-2428) Running cleanup on a node with join_ring=false removes all data

["Chris Goffinet (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-2428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13016569#comment-13016569 ] 

Chris Goffinet commented on CASSANDRA-2428:
-------------------------------------------

If curious why we were running join_ring = false after the node had data, it was because we had ran out of space on a node, and many SSTables had been created, but unable to compact. When we brought the node back online after moving some data off, the number of SSTables being read w/ live traffic caused us to run out of file descriptors. So we decided to run join_ring=false on bootup, and let compaction run without taking on traffic. This worked really well, and we wanted to finalize our cleanup process.

> If you need to bring up a node with join_ring=false for operator maintenance, and this node already has data, it will end up removing the data on the node. We noticed this when we were calling cleanup on a specific CF.
