["Alex Petrov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-13329?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15945324#comment-15945324 ] 

Alex Petrov commented on CASSANDRA-13329:
-----------------------------------------

+1, LGTM

I've written a small test to verify the behaviour [here|https://github.com/ifesdjeen/cassandra/commit/8c2a322bf0bdaf0d198384992caa793f8289b533] although I do not think we should include it into the final patch, since it's rather a configuration/initialisation problem.

And triggered CI for 3.11 and trunk:

> HintsDispatchExecutor creates JMXEnabledThreadPoolExecutor with corePoolSize  == 1 and maxPoolSize==max_hints_delivery_threads and unbounded LinkedBlockingQueue.
> In this configuration additional threads will not be created.
> Same problem with PerSSTableIndexWriter.
