Eric Evans resolved CASSANDRA-6240.
-----------------------------------
Resolution: Fixed
> CLASSPATH logic from init script is unused, JNA isn't loaded
> ------------------------------------------------------------
>
> Key: CASSANDRA-6240
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6240
> Project: Cassandra
> Issue Type: Bug
> Components: Packaging
> Reporter: Faidon Liambotis
> Assignee: Eric Evans
>
> The init script has a classpath() function that collects all the jars and
> even includes this piece of code to work with the standard Debian/Ubuntu
> libjna-jar:
> {code:none}
> # use JNA if installed in standard location
> [ -r /usr/share/java/jna.jar ] && cp="$cp:/usr/share/java/jna.jar"
> {code}
> This seems very nice and correct, however the classpath() function is never
> called and is entirely unused :) Instead, /usr/bin/cassandra is called, which
> in turn includes /usr/share/cassandra/cassandra.in.sh, which has basically
> similar code to collect the jars for CLASSPATH but a) without the JNA
> standard path trick b) without using EXTRA_CLASSPATH (from
> /etc/default/cassandra) at all, so Cassandra boots without either JNA nor
> EXTRA_CLASSPATH, contrary to expectations.
> There are various suggestions on the web to do "ln -s /usr/share/java/jna.jar
> /usr/share/cassandra/lib/"; I suspect this bug to be the reason for that.
> /usr/share/cassandra/cassandra.in.sh seems smart enough to append but not
> overwrite CLASSPATH, so fixing the init script's classpath() to only include
> JNA + EXTRA_CLASSPATH (and making sure it's actually getting called :))
> should be enough for a fix.
