Subject [jira] [Commented] (CASSANDRA-3512) Getting Started instructions don't work in README.txt - wrong version of jamm, wrong path
Date Thu, 28 Mar 2013 20:53:17 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3512?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13616636#comment-13616636
] 

Eugene commented on CASSANDRA-3512:
-----------------------------------

I had this error under CentOS 5 using the RPM packages provided by DataStax.  The issue for
me was '/etc/cassandra/conf/cassandra-env.sh' called jamm using the following:

{noformat}
   cassandra-env.sh:    JVM_OPTS="$JVM_OPTS -javaagent:$CASSANDRA_HOME/lib/jamm-0.2.5.jar"
{noformat} 

However, $CASSANDRA_HOME isn't set anywhere.

I fixed it by adding the following to '/usr/share/cassandra/cassandra.in.sh':

{noformat}
   CASSANDRA_HOME=/usr/share/cassandra
{noformat}

> Download latest release from http://www.apache.org/dyn/closer.cgi?path=/cassandra/1.0.3/apache-cassandra-1.0.3-bin.tar.gz
> Unpack the tarball.
> Follow instructions in README.txt, concluding with:
> {noformat}
> 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/cassandra-env.sh 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.)
