Step24 :- sudo chown -R $USER:$GROUP /var/log/cassandra
Step25 :- export CASSANDRA_HOME=~/cassandra
Step26 :- export PATH=$PATH:$CASSANDRA_HOME/bin
Step27 :- sudo nano ~/cassandra/conf/cassandra-env.sh
JVM_OPTS="$JVM_OPTS –Xss250k“
changing it to:
JVM_OPTS="$JVM_OPTS –Xss350k"
Running Cassandra
Step28 :- sudo sh ~/cassandra/bin/cassandra
Step29 :- sudo sh ~/cassandra/bin/cassandra-cli
