[jira] [Updated] (CASSANDRA-12100) Compactions are stuck after
TRUNCATE
[ https://issues.apache.org/jira/browse/CASSANDRA-12100?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Stefania updated CASSANDRA-12100:
---------------------------------
Status: Patch Available (was: In Progress)
I could not reproduce the problem despite the multiplexed run. There were several compaction interrupted exceptions, but none thrown at the line that would have caused the compaction stats to get stuck.
Nonetheless I think we should commit this patch anyway since it clearly fixes a problem.
It is trivial and it up-merges without conflicts, so I did not run CI on 3.9 and trunk, but I can do so if required.

> Hi,
> since the upgrade to C* 3.0.7 I see compaction tasks getting stuck when truncating the column family. I verified this on all nodes of the cluster.
> Pending compactions seem to disappear after restarting the node.
