Paulo Motta commented on CASSANDRA-13107:
-----------------------------------------
[~weideng] can probably be addressed here. do you have a production cluster or
testbed where you can test the latency impact during compaction of removing
this option in a subset of the nodes? this would be the easier approach.
> 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.
