Subject [jira] [Assigned] (CASSANDRA-3512) Getting Started instructions don't work in README.txt - wrong version of jamm, wrong path
Date Mon, 21 Nov 2011 20:54:51 GMT


Jonathan Ellis reassigned CASSANDRA-3512:

    Assignee: Eric Evans

Right.  That's by design.  Here's the relevant part of bin/cassandra:

# If an include wasn't specified in the environment, then search for one...
if [ "x$CASSANDRA_INCLUDE" = "x" ]; then
    # Locations (in order) to use when searching for an include file.
    for include in /usr/share/cassandra/ \
                   /usr/local/share/cassandra/ \
                   /opt/cassandra/ \
                   "$HOME/" \
                   "`dirname $0`/"; do
        if [ -r "$include" ]; then
            . "$include"
# ...otherwise, source the specified include.
elif [ -r "$CASSANDRA_INCLUDE" ]; then

However, my experience matches yours, that virtually everyone when running bin/cassandra manually
expects it to use the files in bin/ and conf/ rather than "global" package-installed ones.
 (Assigning to Eric for comment since he wrote this.)

> dna@master:~/code/apache-cassandra-1.0.3$ bin/cassandra -f
> Error opening zip file or JAR manifest missing : /lib/jamm-0.2.1.jar
> Error occurred during initialization of VM
> agent library failed to init: instrument
> {noformat}
> Firstly, the version of jamm packaged with Cassandra 1.0.3 is jamm-0.2.5, not jamm-0.2.1.

> Both bin/cassandra.bat and conf/ reference jamm-0.2.5 so not sure where
jamm-0.2.1 is being referenced from - nothing obvious using grep.
> Secondly, /lib/jamm-0.2.1.jar is the wrong path - should be set relative to working directory,
not filesystem root
> (Incidentally, Cassandra v1.0.3 is still listed as unreleased on JIRA.)
