-------------------------------------
Summary: allow different NUMACTL_ARGS to be passed in
Key: CASSANDRA-13557
URL: https://issues.apache.org/jira/browse/CASSANDRA-13557
Project: Cassandra
Issue Type: Improvement
Components: Configuration
Reporter: Matt Byrd
Assignee: Matt Byrd
Priority: Minor
Fix For: 4.x
Currently in bin/cassandra the following is hardcoded:
NUMACTL_ARGS="--interleave=all"
Ideally users of cassandra/bin could pass in a different set of NUMACTL_ARGS if
they wanted to say bind the process to a socket for cpu/memory reasons, rather
than having to comment out/modify this line in the deployed cassandra/bin. e.g
as described in:
https://tobert.github.io/pages/als-cassandra-21-tuning-guide.html
This could be done by just having the default be set to "--interleave=all" but
pickup any value which has already been set for the variable NUMACTL_ARGS.
