[jira] [Commented] (CASSANDRA-13107) Remove
-XX:ThreadPriorityPolicy=42 jvm flag
[ https://issues.apache.org/jira/browse/CASSANDRA-13107?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16143209#comment-16143209 ]
Jeff Jirsa commented on CASSANDRA-13107:
----------------------------------------
Compaction has changed so much since CASSANDRA-1181 that I really dont believe we still need to deprioritize it in 2017. [~krummas] / [~atobey@datastax.com] / [~tjake] , how do you three feel about removing that flag entirely?

> Key: CASSANDRA-13107
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13107
> Project: Cassandra
> Issue Type: Sub-task
> Reporter: Paulo Motta
> Priority: Minor
>
> CASSANDRA-1181 added {{-XX:ThreadPriorityPolicy=42}} jvm flag to support setting native thread priority without root (based on the workaround described on http://tech.stolsvik.com/2010/01/linux-java-thread-priorities-workaround.html).
> On Java9 this wokaround will not longer be possible due to [JEP 245|https://bugs.openjdk.java.net/browse/JDK-8059557] so this flag should be removed.
