[jira] [Commented] (CASSANDRA-10798) C* 2.1 doesn't create dir name with uuid if dir is already present

["Michael Shuler (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-10798?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15035073#comment-15035073 ] 

Michael Shuler commented on CASSANDRA-10798:
--------------------------------------------

The drop/create issue is exactly why 5202 was created. The behavior of using the data in a name-only data directory was for functional upgrades to 2.1 from 2.0.

What behavior are you expecting that addresses 2.0->2.1 upgrades as well as solving 5202?

> on C* 2.1.12 if you create a new table and a directory with the same name already exist under the keyspace then C* will simply use that directory rather than creating a new one that has uuid in the name.
> Even if you drop and recreate the same table it will still use the previous dir and never switch to a new one with uuid. This can happen on one of the nodes in the cluster while the other nodes will use the uuid format for the same table.
> For example I dropped and recreated the same table three times in this test on a two nodes cluster
> node1

> This seems to break the changes introduced by CASSANDRA-5202
