Subject [jira] [Commented] (CASSANDRA-13107) Remove -XX:ThreadPriorityPolicy=42 jvm flag
Date Fri, 06 Jan 2017 17:45:58 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13107?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15805106#comment-15805106

Wei Deng commented on CASSANDRA-13107:
--------------------------------------

Do we need to create a related JIRA to track the need to find another workaround/solution
so that non-root C* process can still lower priority of some threads?

> Remove -XX:ThreadPriorityPolicy=42 jvm flag

>                 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.
