Subject [jira] [Commented] (CASSANDRA-11705) clearSnapshots using Directories.dataDirectories instead of CFS.initialDirectories
Date Tue, 10 May 2016 16:01:13 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11705?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15278336#comment-15278336
] 

Blake Eggleston commented on CASSANDRA-11705:
---------------------------------------------

To prevent {{addInitialDirectories}} from changing {{initialDirectories}} while it's making
a copy to return. Since we copy on write the {{initialDirectories}} value, I could just grab
a reference to {{initialDirectories}} at the top of {{getInitialDirectories}} and copy from
that instead, although both are called infrequently enough that I don't think it would make
a difference.

> An oversight in CASSANDRA-10518 prevents snapshots created in data directories defined
outside of cassandra.yaml from being cleared by {{Keyspace.clearSnapshots}}. {{ColumnFamilyStore.initialDirectories}}
should be used when finding snapshots to clear, not {{Directories.dataDirectories}}
