Ubuntu 12.04 and cassandra install - + HeapDumpOnOutOfMemoryError -Xss128k

Question

I follow the installation instructions for cassandra in Installing Cassandra

When I installed, I will get lower. How can i fix it?

service cassandra start xss = -ea -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms1001M -Xmx1001M -Xmn100M -XX:+HeapDumpOnOutOfMemoryError -Xss128k root@i-157-16647-VM :~# service cassandra status xss = -ea -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms1001M -Xmx1001M -Xmn100M -XX:+HeapDumpOnOutOfMemoryError -Xss128k * Cassandra is not running 

I work on a machine with 2 gigabytes of RAM. This is how I install on a virtual virtual machine.

Answer 1

You have run out of dedicated storage for JAVA VM (128k) too little.

Change the line below (... "128k" ...) to reach a stack size of at least 160k in the file

/opt/cassandra/conf/cassandra-env.sh or /etc/dse/cassandra/cassandra-env.sh

 JVM_OPTS="$JVM_OPTS -Xss160k" 

Answer 2

In my case, doing sudo chown -R cassandra: cassandra / var / lib / cassandra and sudo chown -R cassandra: cassandra / var / log / cassandra helped launch Cassandra. https://issues.apache.org/jira/browse/CASSANDRA-4058#comment-13662604 contains more detailed information on what could lead to this situation.

Answer 3

Just do not trust the cassandra status message , for example:

• Cassandra does not start a message

Just try

$ nodetool -h 127.0.0.1 info

Your Cassandra, maybe OK!

Answer 4

This is mainly possible thanks to the JDK. I met a similar error with the IBM JDK, it works as soon as I replaced the IBM JDK with Oracle JDK.
