I'm trying to do the 'add a node' exercise in DS210.
So I've followed the instructions very carefully, but when I try to start cassandra, I get this:
* Starting DSE daemon dse DSE daemon starting with only Cassandra enabled (edit /etc/default/dse to enable other features) /etc/init.d/dse: 501: ulimit: error setting limit (Operation not permitted) The linux limit 'memlock' is '64'. The minimum recommended is 'unlimited'. Check your configuration. Check our documentation for more details. https://docs.datastax.com/en/dseRecommendedSettings68/ [ OK ] ubuntu@ds210-node3:~$ ulimit -l 64 ubuntu@ds210-node3:~$
If I do 'ulimit -l' on node1, which is running cassandra quite happily, it's also 64.
Any ideas welcome please
