I have installed Cassandra on ubuntu 12.04 .
But when I start it, the following error occurrs:
cassandra -f
xss = -ea -javaagent:/usr/share/cassandra/lib/jamm-0.2.5.jar -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms1493M -Xmx1493M -Xmn373M -Xss160k
Segmentation fault (core dumped)
I did the following to solve it but nothing happens:
in /etc/conf/cassandra-env.sh
I commented the following lines:
JVM_OPTS="$JVM_OPTS -XX:+HeapDumpOnOutOfMemoryError"
# set jvm HeapDumpPath with CASSANDRA_HEAPDUMP_DIR
if [ "x$CASSANDRA_HEAPDUMP_DIR" != "x" ]; then
JVM_OPTS="$JVM_OPTS -XX:HeapDumpPath=$CASSANDRA_HEAPDUMP_DIR/cassandra-`date +%s`-pid$$.hprof"
fi
and ran the following commands on shell as root:
unset IBM_HEAPDUMP
unset IBM_HEAP_DUMP
How should I solve it?

See my answer here, https://stackoverflow.com/a/14447535/92463 which describes increasing the stack segment size to enable Cassandra on OpenJDK.

I had same problem, and found the following:
$ cassandra -f
xss = -ea -javaagent:/usr/share/cassandra/lib/jamm-0.2.5.jar -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms826M -Xmx826M -Xmn100M -XX:+HeapDumpOnOutOfMemoryError -Xss180k
Segmentation fault (core dumped)
ok, how about:
$ sudo cassandra -f
xss = -ea -javaagent:/usr/share/cassandra/lib/jamm-0.2.5.jar -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms826M -Xmx826M -Xmn100M -XX:+HeapDumpOnOutOfMemoryError -Xss180k
..no Segmentation Fault this time, and maybe the 'xss' part is just an obscure debugging message in that case?
$ ps -Af | grep cass
ubuntu 5687 959 0 15:42 pts/0 00:00:00 grep --color=auto cass
hmm, no processes started though.
What did work for me is:
$ sudo /etc/init.d/cassandra start
xss = -ea -javaagent:/usr/share/cassandra/lib/jamm-0.2.5.jar -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms826M -Xmx826M -Xmn100M -XX:+HeapDumpOnOutOfMemoryError -Xss180k
$ ps -Af | grep cass
root 5789 1 0 15:45 ? 00:00:00 jsvc.exec -user cassandra -home [blah blah blah] org.apache.cassandra.thrift.CassandraDaemon
106 5791 5789 13 15:45 ? 00:00:06 jsvc.exec -user cassandra -home [blah blah blah] org.apache.cassandra.thrift.CassandraDaemon
...though I realise that's not running it in the foreground like cassandra -f
is supposed to.
I eventually gave up and started over, avoiding manual installation by just booting an EC2 instance from the DataStax Community AMI: https://aws.amazon.com/amis/datastax-auto-clustering-ami-2-2
But... I just found what looks like the real answer here: https://stackoverflow.com/a/12941854/202168
