Hello Cassandra experts,
I am a newbie to Cassandra. I am trying to evaluate Cassandra using DSE on a CentOS 64 bit os (virtual machine).
Steps I followed:
1. Downloaded latest tarball version of DSE, extracted into /programs/datastax/dse. verified java, python intallations.
2. Configured classpath variables as below
export DSE_HOME=/programs/datastax/dse
export CASSANDRA_HOME=$DSE_HOME/resources/cassandra
export OPSC_HOME=/programs/datastax/opscenter
export PATH=$PATH:$DSE_HOME/bin:$CASSANDRA_HOME/bin:$OPSC_HOME/bin
3. Configured single node cluster by setting
initial_token:0
listen_address:127.0.0.1
data_file_directories: - /programs/datastax/data
saved_caches_directory: /programs/datastax/data/saved_caches
commitlog_directory: /programs/datastax/data/commitlog
in /programsdatastax/dse/resources/cassandra/conf/cassandra.yaml file
and
log4j.appender.R.File=/programs/datastax/data/system.log
in /programsdatastax/dse/resources/cassandra/conf/log4j-server.properties
and trying to start cassandra on foreground, cassandra -f. But i am not able to start cassandra. Please find the terminal output.
[root@localhost bin]# cassandra -f
xss = -ea -javaagent:/programs/datastax/dse/resources/cassandra/lib/jamm-0.2.5.jar -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms494M -Xmx494M -Xmn100M -XX:+HeapDumpOnOutOfMemoryError -Xss180k
