Subject [jira] [Created] (CASSANDRA-13557) allow different NUMACTL_ARGS to be passed in
Date Sat, 27 May 2017 00:20:04 GMT
Matt Byrd created CASSANDRA-13557:
-------------------------------------

             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.
