Eric Evans commented on CASSANDRA-8821:
---------------------------------------
[~mshuler]:
{{debian/init}}:
This is all a throwback to when the init script used {{jsvc}}, and there is a
bit more of it that can be excised; You can also remove the bits that source
{{cassandra-env.sh}}, and the zero-length test of {{$JVM_OPTS}}. See:
CASSANDRA-10251.
{{conf/cassandra-env.\{sh,ps1\}}}:
I don't think we should be promoting the use of {{JVM_EXTRA_OPTS}} from within
{{cassandra-env.*}}. By which I mean, if you are editing one of those files
then it's probably sanest to just edit {{JVM_OPTS}}, and leave
{{JVM_EXTRA_OPTS}} as a way of injecting options from elsewhere. I suggest
that we remove the commented out assignment, adjust the documenting comments
accordingly, or remove them entirely. You can put a commented out
{{JVM_EXTRA_OPTS}} assignment, and corresponding documentation in
{{debian/default}}.
Does this sounds reasonable?

> Key: CASSANDRA-8821
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8821
> Project: Cassandra
> Issue Type: Bug
> Environment: Ubuntu 14.04 LTS amd64
> Reporter: Terry Moschou
> Assignee: Michael Shuler
> Priority: Minor
> Fix For: 2.1.x, 2.2.x
>
> Attachments: 8821_2.0.txt, 8821_2.1.txt

>
> Repos:
> deb http://www.apache.org/dist/cassandra/debian 21x main
> deb-src http://www.apache.org/dist/cassandra/debian 21x main
> The cassandra init script
> /etc/init.d/cassandra
> is sourcing the environment file
> /etc/cassandra/cassandra-env.sh
> twice. Once directly from the init script, and again inside
> /usr/sbin/cassandra
> The result is arguments in JVM_OPTS are duplicated.
> Further the JVM opt
> -XX:CMSWaitDuration=10000
> is defined twice if jvm >= 1.7.60.
> Also, for the environment variable CASSANDRA_CONF used in this context
> -XX:CompileCommandFile=$CASSANDRA_CONF/hotspot_compiler"
> is undefined when
> /etc/cassandra/cassandra-env.sh
> is sourced from the init script.
> Lastly the variable cassandra_storagedir is undefined in
> /usr/sbin/cassandra
> when used in this context
> -Dcassandra.storagedir=$cassandra_storagedir
