I am using upsource-3.5.3616.
I made a memory setting change to /var/upsource-3.5.3616/conf/cassandra/cassandra.jvmoptions.dist. However, when running, a warning reads:
WARNING! The "/var/upsource-3.5.3616/conf/cassandra/cassandra.jvmoptions.dist" file was changed. If you changed it manually you should change the "/var/upsource-3.5.3616/conf/cassandra/cassandra.jvmoptions" file instead, otherwise just ignore this message.
However, there is no file exists at /var/upsource-3.5.3616/conf/cassandra/cassandra.jvmoptions.
So any suggestion on how to make memory changes? Also, how to verify how much memory cassandra is actually configured/using?
