Subject [jira] [Commented] (CASSANDRA-10421) Potential issue with LogTransaction as it only checks in a single directory for files
Date Thu, 08 Oct 2015 09:36:26 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10421?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14948380#comment-14948380

Sylvain Lebresne commented on CASSANDRA-10421:
----------------------------------------------

bq. If rc2 is end of the week I think it's going to be hard to get to +1 for a new sub-system
and patch like this.

Just as a fyi, we're now aiming at the end of next week (so Friday 16th) for rc2. Still, we
need to figure this out pretty quickly.

> When creating a new LogTransaction we try to create the new logfile in the same directory
as the one we are writing to, but as we use {{[directories.getDirectoryForNewSSTables()|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/db/lifecycle/LogTransaction.java#L125]}}
this might end up in "any" of the configured data directories. If it does, we will not be
able to clean up leftovers as we check for files in the same directory as the logfile was
created: https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/db/lifecycle/LogRecord.java#L163
