Cassandra can't find jamm on startup
------------------------------------
Key: CASSANDRA-2647
URL: https://issues.apache.org/jira/browse/CASSANDRA-2647
Project: Cassandra
Issue Type: Bug
Components: Packaging
Environment: Ubuntu 10.04 Lucid
Reporter: Marcus Bointon
I installed the Debian package (from
http://www.apache.org/dist/cassandra/debian unstable) of Cassandra 0.8beta2 on
Ubuntu 10.04 with the sun jdk over a working copy of 0.7.2. It broke on restart.
On startup it gives this:
{code}
Error occurred during initialization of VM
agent library failed to init: instrument
Error opening zip file or JAR manifest missing : /lib/jamm-0.2.2.jar
{code}
/etc/cassandra/cassandra-env.sh contains this:
{code}
# add the jamm javaagent
check_openjdk=$(java -version 2>&1 | awk '{if (NR == 2) {print $1}}')
if [ "$check_openjdk" != "OpenJDK" ]
then
JVM_OPTS="$JVM_OPTS -javaagent:$CASSANDRA_HOME/lib/jamm-0.2.2.jar"
fi
{code}
By default, CASSANDRA_HOME is not set, so it's looking in /lib for this jar. It
seems CASSANDRA_HOME should be set to /usr/share/cassandra, since that's where
jamm-0.2.2.jar is installed, but that means the path is still wrong.
I set CASSANDRA_HOME to /usr/share/cassandra and changed the JVM_OPTS line to
this:
{code}
JVM_OPTS="$JVM_OPTS -javaagent:$CASSANDRA_HOME/jamm-0.2.2.jar"
{code}
and then cassandra started ok.
Is this a bug or did I miss something?
I also noticed that this line appears to be the only use of CASSANDRA_HOME.
